Brussels, 15/01/2018, With special authorization: BE2016 / 5517 -1 ADHESIVE AND / OR SEALANT COMPOSITION SCOPE OF THE INVENTION The present invention relates to an improved method of manufacturing an adhesive and / or sealant composition with a high initial tack. The present invention further relates to an adhesive and / or sealant composition having a high initial tack and its use in bonding, sealing or coating materials. Background of the invention Adhesive and / or sealant compositions have many uses, for example in bonding, sealing or coating materials. Many adhesive and / or sealant compositions include reactive silane-modified polymer systems in which the silane groups include hydrolyzable groups. These silane-modified polymers are capable of condensing together, even at room temperature, by eliminating the hydrolyzable groups. Depending on the number of hydrolyzable groups and their construction, the products are mainly long chain polymers (thermoplastics), relatively coarse-mesh three-dimensional networks (elastomers) or highly cross-linked systems (thermosets). Such adhesive and / or sealant compositions comprising reactive silane-modified polymer systems are disclosed in particular in U.S. Pat. Nos. 2015/0203624 A1, EP 0240044 A2, WO 2004/090060 A2, EP 1043356 A1, EP 2581406 A1, and WO 2006 / 078756 A1. Adhesive and / or sealant compositions often require a high initial tack. The term "initial tack" as used herein refers to the tack value measured immediately after application of the adhesive and / or sealant composition before cross-linking and / or curing the composition. Adhesive and / or sealant compositions with high initial tack are required in applications where good strength and low sag behavior are required. Such applications include, for example, the use of an adhesive and / or seal BE2016 / 5517 - Composite composition in oblique or vertical zones, as well as applications where movement of the parts to be secured together by means of the adhesive and / or sealant composition during curing of the composition is undesirable. High initial tack on an uncured composition should not be confused with a high "initial tack" as obtained with classic two-component formulations, where the second component is used to accelerate curing after application, and where there is still a period of time is (usually from minutes to hours) with the resulting mixture exhibiting low initial tack properties. One of the drawbacks of these adhesive and / or sealant compositions with a high initial tack is that production of the compositions is very problematic. Due to the high tack and high viscosity of the compositions, mixing and pumping of the material to subsequent processes can be particularly cumbersome. It is known that adhesive and / or sealant compositions often do not exhibit adequate initial tack properties. Both one- and two-component adhesive and / or sealant compositions are in need of improvement in this regard. Due to the insufficient initial tack, immediately after the parts to be fastened together are joined, the fastened parts must be mechanically fixed until the adhesion has developed sufficient strength. Another drawback of known one- and two-component adhesive and / or sealant compositions is that the initial tack and viscosity increases to such an extent that the application or production of the composition is hindered. For two-component adhesive and / or sealant compositions with a high initial tack, often one, or both, has such a high initial tack and such a high viscosity that mixing a relatively viscous component with a relatively liquid component (which is less viscous and has a lower initial tack), or the menBE2016 / 5517 -3gen of two relatively viscous components, is hindered. There is not enough compatibility between the two components to easily achieve a homogeneous mixing. Since thorough mixing is required to obtain efficient and rapid activation of the silane-modified polymer systems, this implies that specialized and expensive instruments are required for homogeneous mixing of the two components, which is not advantageous. Patent WO 2014/033273 A2 relates to a one and two component adhesive composition having a high initial tack, comprising a moisture crosslinking silyl modified polymer and an organoclay based rheology adjuster which is an alkyl ammonium salt modified mineral clay blend and a process for producing the adhesive composition. Patent WO 2014/033273 A2 provides 1K adhesive compositions of relatively low viscosity, the viscosity of which increases to the desired value for an early strength, or tack, after application when the adhesive compositions are exposed to water, that the organoclay-based rheology adjuster activates. The patent WO 2014/033273 A2 further describes two-component adhesives that have a low viscosity on application, the thickening effect taking place after the combination of the two components. However, this process requires the use of an organoclay based rheology modifier. To ensure proper dispersion of such organoclay-based rheology adjusting agents, high shear forces are usually required. When the dispersion is not sufficient, there is a risk of crystal seed formation, the uncured liquid compositions tend to turbidity, and adverse effects of gloss and haze occur in the final cured product. In the patent WO 2014/033273 A2, the process is not described as a flexible process in which the initial tack of the adhesive composition is finely adjustable over a wide range. BE2016 / 5517 U.S. Patent US 2012/0298300 A1 relates to moisture curable compositions based on silane functional polymers, which are suitable as adhesives, sealants or coatings, and which may exhibit improved initial strengths. However, U.S. Patent US 2012/0298300 A1 does not imply a method of manufacturing a one and two component adhesives and / or sealant composition with a high initial tack. In addition, the adhesives disclosed in U.S. Patent No. 2012/0298300 A1 are hot or hot melt adhesives that are to be heated and melted at a high temperature in use, and thus require a heat coater. In addition, the type of objects that can be bonded using this adhesive is usually quite limited. No initial tack values are disclosed. Patent EP 0819749 A2 relates to an adhesive or sealant composition having a high initial tack, comprising a moisture-crosslinking polymer and rheology adjusting agent. Patent EP 0819749 A2 furthermore relates to a process for the production of the adhesive or sealant composition. The rheology adjuster increases the viscosity of the adhesive and thereby provides the final product with sufficient initial tack, but only after thermal activation of the rheology adjuster. The patent EP 0819749 A2 states that the preferred minimum storage modulus is 200 kN / m 2 . However, no initial tack values are disclosed. The disadvantage of this process, however, is that the rheology adjusting agent is only activated after application of heat to the final product, which means that the adhesive composition only shows a high initial tack after application of heat, which adds an extra step to the production process and therefore impractical and economically less advantageous. Accordingly, there remains a need for a flexible method of manufacturing an adhesive and / or sealant composition that provides the adhesive value of the adhesive and / or sealant composition BE2016 / 5517 -5 setting is finely adjustable over a wide range, making it possible to obtain very high adhesion values. In addition, there is a need for an economically more advantageous and more practical method of manufacturing the adhesive and / or sealant composition with such high tack without the use of specialized equipment and without organoclay-based or heat-activatable rheology setting means are needed. Summary of the invention The applicant has now found a method of manufacturing an adhesive and / or sealant composition that allows the adhesive value of the adhesive and / or sealant composition to be fine-tuned over a wide range, including high tack values, and to meet the above-mentioned needs. surprisingly effective way.

BE2016 / 5517 -16 Applicants prefer to use a GPC device for determining molecular weights (M w ). Preferably, the GPC / SEC device that is part of the Agilent 1200 Infinity Series LC is used, equipped with a 1200 Series isocratic pump, a standard automatic sampling device for volumes between 0.1 and 100 microliters, a SECcurity GPC column oven TCC6000, the 1200 Series Variable Wavelength UV detector, a SECcurityonline two-channel degasser for eluent degassing, the WinGPC Unity Software for peak integration and an analytical GPC column set consisting of the following columns in series: 2 x GPC columns PSS SDV analytical, 3 µm, 100 A, 300 x 8.0 mm followed by 2 x GPC columns PSS SDV analytical, 3 µm, 1000 A, 300 x 8.0 mm. The pump is preferably set to flow at 1,000 (one) ml / minute, with tetrahydrofuran (THF) as the eluent. The UV detector is preferably set for a wavelength of 254 nm. Further preferred settings include an injection volume of 25 microliters, a column temperature of 30 ° C. Preferably, the samples are prepared by dissolving them in a diluent, resulting in a sample concentration of about 4 micrograms / microliter. The preferred diluent is tetrahydrofuran (THF), 99.9%, extra pure, anhydrous, stabilized with butylhydroxytoluene (BHT) obtained from Acros, and toluene, 99.85%, additionally dried over a molecular sieve also obtained from Acros. The toluene acts as an internal flow marker. Preferably, the sample is given at least 30 minutes to allow complete dissolution in the sample diluent. It is then filtered through a 25 mm polytetrafluoroethylene filter (PTFE filter) with a pore size of 0.2 micrometers to remove any insoluble material present that could contaminate or block the GPC device. During this preparation of the sample, contact with water or atmospheric moisture should be avoided as much as possible, as this may affect the result of the measurement. It is known to a person skilled in the art that the most important information obtained from the GPC UV detector is not the molecular weight, but the apparent concentration at a given elution volume. When one out BE2016 / 5517 In order to determine molecular weight distributions, a calibration of the GPC is required based on assigning the elution volume to a given molecular weight. The most common method for this calibration, which is preferred by the applicant, is the method which uses molecular weight standards with a narrow molecular weight distribution, for example polystyrene standards such as the 'ReadyCal PS' series, which is available from the company PSS in Germany. The elution volumes of the standards are then measured and plotted against the logarithm of the molecular weight at the peak maximum of each analytical standard. An appropriate fit function should also be selected, which adequately describes the shape of the calibration curve. Using this fitting function, the molecular weight distribution (with respect to polystyrene) and their respective average molecular weights, ie M n and M w , can then be calculated. In a preferred embodiment of the method of the present invention, the weight percentage of the silane-modified polymer (P) used in step 1, relative to the total weight of the composition (C), is advantageously equal to or greater than 5 weight %, preferably equal to or greater than 10% by weight, more preferably equal to or greater than 15% by weight.

Preferably, the standard method used to determine the BET area of the hydrophobic fumed silicas (S) is the standard DIN 66131.

For example, suitable hydrophobic fumed silicas (S) can be produced by treating hydrophilic fumed silicas with a hydrophobizing agent such as organosilanes or organosiloxanes [hereinafter referred to as "hydrophobizing agent (HA)"]. The silica surface is chemically modified in that process, i.e., the hydrophobizing agent is bonded to the silica by chemical bonds to form a hydrophobic silica (S). Preferably, the hydrophobizing agents (HA) can be selected from octamethylcyclotetrasiloxane, polydimethylsiloxane, dimethylsiloxane, BE2016 / 5517 Monomethyltrichlorosilane, dimethyldichlorosilane, trimethylchlorosilane, hexamethyldisilazane, or alkyl silanes, such as, but not limited to, octyl trialkoxy silanes, hexyl trialkoxy silanes.

In order, the adhesive force values to objectively quantify, in the context of the present invention, the adhesive force can be T o and T are determined by means of the adhesive strength test method which is described in detail in the experimental section. The adhesive strength values T and T o can be suitably determined by an oscillating rheological measurement in which a sinusoidal stress deformation is applied and the resulting stress response is measured using an HR-2 Discovery Hybrid Rheometer from TA Instruments, or an equivalent known to those skilled in the art. Without being bound by this theory, the inventors have found that the advantage of using an oscillating rheological measurement lies in the fact that the sample may not be destroyed during the measurement, and that valid results can therefore be obtained, in contrast to rotary rheological measurements, where the samples can often tend to deform and / or tear.

BE2016 / 5517 The inventors have been surprised to find that the tack value T of the method of the present invention can be finely adjusted over a wide range through the careful selection of a particular rheology modifier (R), as illustrated in the experimental section. In other words, this demonstrates the flexibility of the method of the present invention.

Good results were obtained when the weight percentage of the rheology adjuvant (R), relative to the total weight of the composition (C), is between 0.5-3% by weight. Composition (C) As already mentioned, the present invention provides a method of manufacturing a composition (C) suitable for use as an adhesive and / or sealant, wherein the composition (C) as obtained in step 2 has an adhesive value T measured in accordance with the adhesion test, where: T> (equation 1) BE2016 / 5517 -37 and K is equal to or greater than 6000 Pa, and L is equal to or greater than 1000 Pa. According to certain embodiments of the method of the present invention, the value K in equation 1 (eq. 1) for the tack value T of the composition (C) as obtained in step 2 is advantageously equal to or greater than 7000 Pa , preferably equal to or greater than 8000 Pa, more preferably equal to or greater than 9000 Pa, even more preferably equal to or greater than 10000 Pa, even more preferably equal to or greater than 11000 Pa, most preferred equal to or greater than 12000 Pa.

Thorough mixing of the mixture (M), as explained above, with at least one rheology modifier (R), as explained above, can BE2016 / 5517 -38 are performed using various conventional mixing techniques known to those skilled in the art. Preference is given to a mixing technique with low shear forces. The inventors have surprisingly found that when the mixing is performed with excessive shear, the adhesive value and the viscosity of the mix decrease. Those skilled in the art can make appropriate decisions and / or experimentally determine suitable mixing conditions whereby mixing is performed with low shear forces. In typical situations, mixing of the mixture (M), as explained above, with the at least one rheology adjuster (R), as explained above, is performed using static mixers, ribbon mixers, V mixers, continuous processing equipment, cone screw mixers , screw mixers, double cone mixers, double planet mixers, dissolving mixers, high viscosity mixers, counter rotation mixers, double and triple shaft mixers, vacuum mixers, dispersion mixers, paddle mixers, jet mixers, mobile mixers, drum mixers, intermediate mixers, high intensity mixers dual asymmetric centrifugal mixers such as, in particular, SpeedMixer ™ mixers, and the like in order to obtain a physical mixture. When a dual asymmetric centrifugal mixer, such as a SpeedMixer ™, is used, the mixing speed as used in step 1 of the method of the present invention is advantageously equal to or less than 5000 rpm, more preferably equal to or less than 4000 rpm, with still more preferably equal to or less than 3000 rpm, most preferably equal to or less than 2700 rpm. Furthermore, it should be known that the lower value of the mixing speed as used in step 1 is not particularly limited but advantageously equals or exceeds 500 rpm, preferably equals or exceeds 1000 rpm, more preferably equal to or greater than 1500 rpm, even more preferably equal to or greater than 2000 rpm, most preferably equal to or greater than 2500 rpm. Good results were obtained BE2016 / 5517 -39 reached when the mixing speed as used in step 1 is between 2500 and 2700 rpm. When using a dual asymmetric centrifugal mixer, such as a SpeedMixer ™, the mixing time as used in step 1 of the method of the present invention is advantageously equal to or less than 100 seconds, more preferably equal to or less than 50 seconds, most preferably equal to or less than 40 seconds. Furthermore, it should be known that the lower value of the mixing time as used in step 1 is not particularly limited but advantageously equals or exceeds 5 seconds, preferably equals or exceeds 15 seconds, more preferably equal to or greater than 25 seconds. Good results were obtained when the mixing time as used in step 1 is between 25 and 40 seconds. Advantageously, the time between step 1 and step 2 of the method of the present invention is equal to or less than 15 minutes, more preferably equal to or less than 10 minutes, even more preferably equal to or less than 5 minutes. Furthermore, it should be known that the lower value of the time between step 1 and step 2 of the method of the present invention is not particularly limited. The order of addition of each component, the mixture (M) and the at least one rheology adjusting agent (R) is not particularly limited in the respective composition (C). Generally, however, the mixture (M) is first added to the mixer, and then the rheology adjusting agent (R) is added. The inventors have surprisingly found that the initial tack value of an adhesive and / or sealant composition can be drastically increased in step 2 of the manufacturing process, this step 2 comprising mixing the mixture (M) with a rheology adjuster (R). The increase in the tack value from tack value T o to T takes place only in the final stage (step 2), thus providing the method of the present invention with a more practical method of manufacturing adhesive and / or sealant compositions with BE2016 / 5517 -40 a high tack value T. The pumpability of the mixture (M) is not disadvantageous and requires little energy, which then mainly improves the handling of the mixture (M). Furthermore, the method according to the present invention is economically more advantageous. As already mentioned, the increase in the tack value from tack value T o to T does not occur until the last stage (step 2), so no specialized equipment is required to perform the mixing steps. In addition, in order to achieve the tack value T, it is not necessary to use organoclay based rheology setting agents, and it is not necessary to use rheology setting agents which are activated by heat. Another significant advantage of the method of the present invention resides in the fact that it is a flexible method. The method of the present invention allows fine adjustment of the adhesive value T in a very wide range, on the one hand by carefully selecting the hydrophobic fumed silica (S) used in step 1, on the other hand by carefully selecting the rheology modifier (R) used in step 2. The tack value T can be measured in accordance with the tack test method, as explained above and discussed in detail in the experimental section. In certain embodiments of the method of the present invention, the tack value T of the composition (C), measured in accordance with the tack test method, is equal to or greater than 1000 Pa, more preferably equal to or greater than 2500 Pa, with still more preferably equal to or greater than 5000 Pa, even more preferably equal to or greater than 6000 Pa, even more preferably equal to or greater than 7000 Pa, even more preferably equal to or greater than 8000 Pa, even more preferably equal to or greater than 9000 Pa, even more preferably equal to or greater than 10000 Pa, even more preferably equal to or greater than 11000 Pa, most preferably equal to or greater than 12000 Pa. Furthermore, it should be clear that the adhesive value T of the composition (C), BE2016 / 5517 -41 measured in accordance with the adhesion test method, is not particularly limited but is advantageously equal to or less than 30000 Pa, preferably equal to or less than 25000 Pa, more preferably equal to or less than 20000 Pa. According to certain embodiments of the method of the present invention, the tack value T of the composition (C) as obtained in step 2 is a high tack value T, measured in accordance with the tack test method, and is equal to or greater than 8500 Pa, more preferably equal to or greater than 9000 Pa, more preferably equal to or greater than 9500 Pa, even more preferred equal to or greater than 10000 Pa, even more preferred equal to or greater than 10500 Pa, even more preferred equal to or greater than 11000 Pa, most preferably equal to or greater than 12000 Pa. Furthermore, it should be understood that when the tack value T is a high tack value T, measured in accordance with the tack test method, the upper limit of the tack value T of the composition (C) obtained in step 2 is not limited, but advantageously is equal to or less than 30000 Pa, preferably equal to or less than 250000 Pa, more preferably equal to or less than 20000 Pa. According to certain embodiments of the method of the present invention, the tack value T of the composition (C) as obtained in step 2 is a medium tack value T, measured in accordance with the tack test method, and is equal to or greater than 1000 Pa, preferably equal to or greater than 2000 Pa, more preferably equal to or greater than 3000 Pa, even more preferably equal to or greater than 4000 Pa, most preferably equal to or greater than 5000 Pa. Furthermore, it should be understood that when the tack value T is a medium tack value T, measured in accordance with the tack test method, the upper limit of the tack value T of the composition (C) obtained in step 2 is not limited, but advantageously is equal to or less than 12000 Pa, preferably equal to or less BE2016 / 5517 -42 than 11000 Pa, more preferably equal to or less than 10000 Pa, even more preferably equal to or less than 9000 Pa, most preferably equal to or less than 8500 Pa.

BE2016 / 5517 -45 According to certain embodiments, in any of the steps of the method of the present invention, other conventional additional ingredients [hereinafter referred to as "ingredient (I)"] may be added to improve appearance, storage, transportation , handling and / or performance of the product. These ingredients (I) are known to those skilled in the art of adhesive / sealant compositions. Typical ingredients (I) may include, but are not limited to, the following: Stabilizers to protect against light, heat, and / or UV radiation; blowing agents; solvents; fire retardants; pigments; curability modifying agents; radical inhibitors; metal deactivators; antiozonants; phosphorus peroxide-depleting agents; lubricants; adhesion promoters and cross-linking agents such as epoxy silanes, (meth) acrylic silanes, anhydrosilanes or hydroxyl functional silanes, such as are particularly described in the patents WO 2009/130298 A1 and WO 2014/187865 A1; moisture absorbers such as vinyl trimethoxysilane, α-functional silanes such as N- (silylmethyl) -Omethyl carbamates, for example N- (methyl dimethoxysilylmethyl) -Omethyl carbamate, (methacryloxymethyl) silanes, methoxymethylsilanes, N-phenyl, N-cyclohexyl esters and calcium oxylsilanes or molecular sieves; surfactant substances such as wetting agents, leveling agents, deaerators or defoamers; biocides such as algicides, fungicides or antifungal agents; and other substances common in moisture-curing compositions. Typically, the amount of the ingredient (I), if present, is from 0.05 wt% to 20 wt%, more preferably from 0.1 wt% to 10 wt%, most preferably from 0.1 wt% up to 5% by weight, relative to the total weight of the composition (C). Furthermore, it should be understood that all definitions and preferences as described above for the composition (C) as obtained in step 2 of the method of the present invention apply equally to this embodiment and all further embodiments as described below. BE2016 / 5517 -46 Another aspect of the present invention is the composition (C) prepared by the method of the present invention. Yet another aspect of the present invention is an adhesive and / or sealant comprising the composition (C) as set forth above. When applying the composition (C) as obtained in step 2 of the method of the present invention, as described above, the silane groups (SG) of the silane-modified polymer (P) come into contact with ambient moisture. The silane groups (SG) are characterized in that they hydrolyze on contact with moisture. This leads to the formation of organosilanols and, by subsequent condensation reactions, to organosiloxanes. As a result of these readies, which can be accelerated through the use of catalysts, the composition is cured. This process is also called whey "cross-linking". The present invention further relates to a cured composition (C) which is available based on the composition (C) as described above. It is important for the corresponding final applications that the composition (C), as set forth above, remains substantially moisture-free to avoid premature cross-linking. The term "substantially moisture-free," as used herein, means that although the composition (C) may contain some moisture, the amount of moisture is not sufficient to effect significant curing of the composition (C). Accordingly, the composition (C), as obtained in step 2 of the method of the present invention, is preferably stored for storage in a water-impermeable container, in order to isolate the composition (C) from ambient moisture. For example, the composition (C) is preferably packed in an airtight container to protect it from ambient moisture. A suitable impermeable material for the container is high density polyethylene or polyethylene coated with aluminum foil. The container has a suitable shape of a drum, a bag, a paBE2016 / 5517 -47 throne, or the shape of a sausage, respectively, these shapes being suitable for use in combination with application aids. Typically, the composition is storage stable, ie it can be stored in a suitable container or device for the duration of several months up to a year and longer, excluding moisture, without changing to a degree relevant to its use with regarding its application properties or regarding its properties after curing. Preferably, the composition (C) is stored as such in one container (one-component system). For example, in a one-component system, a container can be prepared by performing step 2, which involves mixing the mixture (M) and the rheology adjusting agent (R) and forming the composition (C) just before the introduction of the composition (C) in the container. This avoids problems during the production process, for example when pumping the composition (C) with high tack. Alternatively, in a one-component system, a container can be prepared by performing step 2 in the container, adding the mixture (M) and rheology adjusting agent (R) to the container and shaking the container to mix the contents well, forming the composition (C) inside the container. If desired, instead of storing composition (C) in one container and thus using a one-component system, a two-component system can be used in which each of the components of composition (C), mixture (M) as obtained in step 1 and the rheology adjuster (R) as used in step 2 be packaged separately, in separate containers or in separate chambers from a single container. In the two-component system, step 2, which involves mixing the mixture (M) with a rheology adjusting agent (R), is performed at the time of application, when the first component is mixed with the second component, thereby making the composition (C ) is formed. It should be clear BE2016 / 5517 -48 that the first component may comprise the mixture (M) and the second component may comprise the rheology modifier (R), or vice versa. An advantage of the two-component systems, according to the method of the present invention, is that no specialized mixing equipment is required, since both components have a relatively low tack value and are therefore easy to supply, mix and apply. In the case of two-component systems, a chemical cure can be effected by the reaction of the first component with the second component, further optionally comprising water or hydroxyl functional molecules. In that case, the curing reaction usually proceeds faster. A treatment method An additional object of the present invention is to provide applications of said one and two-component adhesive and / or sealant systems with a high initial tack. The inventors have been surprised to find that not only the properties of the non-cross-linked silane-modified polymers (P) or of the compositions (C) (tack, viscosity, melting point, solubilities, etc.), but also the properties of the cross-linked adhesive / sealant compositions (hardness, elasticity, tensile strength, elongation at break, resistance to heat, etc.) can be tailored to suit the requirements virtually. Therefore, the possibilities for using the composition (C) as produced by the method of the present invention are equally diverse. For example, the compositions (C) as obtained in step 2 can be used to produce elastomers, sealants, adhesives, elastic adhesive systems, rigid and flexible foam products, any of a wide variety of coating systems, or for pressure joints. These products can be applied in any form, such as by lubrication, spraying, pouring, pressing, scraping, etc. BE2016 / 5517 As mentioned, the curing of the composition (C) occurs on contact with moisture. The moisture required for curing can come from the air (humidity), or the composition (C) as obtained in step 2 of the method of the present invention, as described above, can be contacted with a component that contains water, for example by coating it, for example with a finishing soap, or by spraying it; or a component containing water can be added to the composition (C) during application, for example, in the form of an aqueous gruel which is mixed through it, for example, using a static mixer. When cured by moisture, the composition cures cures from the outside to the inside. The rate of the curing process is determined by various factors, such as the diffusion rate of water, the temperature, the moisture content in the atmosphere and the adhesion geometry, and usually slows down as the curing progresses. The inventors have found that the composition (C) as obtained in step 2 of the method of the present invention is typically suitable as an adhesive or sealant, especially for applications requiring a composition with a high initial tack and a low tendency to sag. For example, the composition (C) as obtained in step 2 of the method of the present invention is used in a method of bonding two Substrates or at least a portion of two Substrates. Thus, another aspect of the present invention is a method of bonding two Substrates or at least part of two Substrates using the composition (C), the method comprising the following steps: i) applying the composition (C), according to the above description, to at least a part of a substrate S1 and / or at least a part of a substrate S2; BE2016 / 5517 -50ii) contacting at least a portion of Substrates S1 and S2 through the applied composition (C); iii) curing the composition (C) using water, for example in the form of moisture or hydrated salt particles, thereby forming a cured composition (C); where Substrates S1 and S2 may be the same or different from each other. In addition, the composition (C) as obtained in step 2 of the method of the present invention can also be used in a method of sealing or coating. Thus, another aspect of the present invention is a method of sealing or coating, using the composition (C), the method comprising the following steps: i ') applying the composition (C), according to the above description, to at least a part of a substrate S1 and / or between at least a part of two Substrates S1 and S2; ii ') curing the composition (C) using water, for example in the form of moisture or hydrated salt particles, thereby forming a cured composition (C); where Substrates S1 and S2 may be the same or different from each other. In the case of a two-component system, step i) or i ') of applying the composition (C) is preceded by a step of mixing the two components, thereby forming the composition (C), as described above. Suitable Substrates S1 and / or S2 are, for example, Substrates which may be selected from the group consisting of concrete, mortar, clinker stone, brick, pottery, plaster, natural stone such as granite or marble, glass, glass pottery, metal or metal alloys such as aluminum, steel, non-ferrous metal, galvanized metal, wood, plastics such as PVC, polycarbonate, polymethyl (meth) acrylate, polyester, epoxy resin, paint and lacquer. The articles to be adhered, sealed or coated with the composition (C) as obtained in step 2 of the method according to onBE2016 / 5517 The present invention can be, for example, an industrially manufactured good or a consumer product, for example a window or facade, solar panels, a household appliance, or a means of transport, for example a vehicle, or a vehicle attachment, trunk boxes, caravans, and the like. The composition (C) as obtained in step 2 of the method of the present invention can be applied to the substrate using a suitable aid, for example in the form of a pearl with, for example, an essentially circular or triangular cross section . Suitable methods of applying the composition (C) as described above include, for example, application from commercial cartridges, which can be operated manually or using compressed air, or from a drum or bucket using a pump or an extruder. device, possibly with the aid of an application robot. The composition (C) as described above, with good application properties, has high stability and short filament formation. This means that it remains in the applied form after application, i.e. does not run out, and after removal of the application device it does not form a thread or only a very short thread, so that the substrate does not become dirty. EXPERIMENTAL TEST RESULTS The invention will now be described in more detail by the following examples, the purpose of which is merely illustrative and which are not intended to limit the scope of the invention. General procedure for determining the tack values T and Tn using the tack test method The tack values T and T o were determined by an oscillating rheological measurement applying a sinusoidal stress distortion and measuring the resulting stress response.

This Peltier plate was connected to a Peltier CirculaBE2016 / 5517 -52tor Thermo Cube Model 10-300. The HR-2 Discovery Hybrid Rheometer was calibrated according to the manufacturer's procedure for starting measurements or when the stainless steel top rotary plate was removed for cleaning. The samples (e.g. mixture (M) or composition (C), for example) were free from visual impurities and air bubbles and were brought to room temperature (23 ± 1 ° C). Measurement parameters: Temperature = 20 ° C Soaking time = 10 seconds Frequency ω = 1 Hz Diameter d of stainless steel top rotatable plate = 25 mm Shear stress range from 6.5 Pa to 17000Pa Method: a. The temperature of the bottom Peltier plate was stabilized at 20 ° C b. the gap between the two plates was closed by lowering the top rotatable stainless steel plate c. in the software, the gap of the measuring system was set to zero d. the top rotatable stainless steel plate was moved up and the sample (e.g. Mixture (M) or e.g. composition (C)) was applied to the bottom plate using a stainless steel spatula, the amount of the sample being such that a 1000 µm gap between the two plates was completely filled e. the stainless steel top rotatable plate was moved down to a 1010 µm slit, the sample being trimmed by removing the excess sample that was squeezed out around the edges of the two plates, using a stainless steel spatula steel. BE2016 / 5517 -53f. the stainless steel top rotatable plate was further lowered to a 1000 µm slit and the measuring system locked g. a 10 second soak time was observed to equilibrate the sample with the temperature of the bottom Peltier plate, 20 ° C h. a logarithmic gradual change of the shear stress was performed over a range of 6.5 Pa to 17000 Pa with 10 measuring points per decade i. the tack value was read on the voltage scale when the phase angle δ reached 45 °; when the sample showed no tack at all or the tack was too low to measure, a tack value of 0 Pa was assigned j. the top plate was raised and the plates were cleaned with a suitable solvent such as isopropanol or acetone. The obtained tack values T are listed in Tables 2 to 6. General procedure for producing a composition (C) according to the invention. In step 1, a mixture (M) according to the invention was prepared by mixing a silane-modified polymer (P) according to the invention with a hydrophobic fumed silica (S) according to the invention, optionally with a plasticizer (PL) and / or optionally with an ingredient (I) according to the invention, in a Hauschild Speedmixer ™ (DAC 150.1FVZ) at 2600 rpm for 30 seconds.

Most of the mixtures (M) showed a very low tack value T o or no tack T o at all (tack value T o of 0 Pa). All tack values T of Examples 7 to 15 meet the requirements of Equation 1 as set forth above in the description. Different between the different hydrophobic fumed silicas (S) were characterized in function of the hydrophobizing agent (HA) used. As shown in Table 3, depending on the desired tack value T, a different hydrophobic fumed silica (S) can be selected. For example, a high tack value T was obtained with hydrophobic fumed silicas (S) treated with octamethylcyclotetrasiloxane. A medium tack value T was obtained with hydrophobic fumed silicas (S) treated with dimethyl dichlorosilane. The use of a hydrophilic fumed silica, in Example 16 for comparison, resulted in a decrease in the tack value T, demonstrating the importance of the hydrophobicity of the fumed silicas.
