    Sealant sealant and / or adhesive sealant composition with silane-modified polymers
    TECHNICAL FIELD
    The present invention relates to a sealant and / or adhesive sealant composition with silane-modified polymers, to a method of producing a sealant sealant and / or adhesive sealant composition with silane-modified polymers, to a use of the method for producing a sealant-modified polymers and / or adhesive sealant composition, and on a kit comprising a sealant sealant and / or adhesive sealant composition with silane-modified polymers enclosed in an airtight container.
    BACKGROUND
    A sealant and / or adhesive sealant composition comprising silane-modified polymers combines the adhesive strength of a polyurethane adhesive with the elasticity of a silicone sealant. It is therefore also possible to speak of a hybrid system. It concerns a system in which the advantages of polyurethanes (including a high adhesive strength) and silicone (including heat conductivity and high resistance to the action of oxygen and ultraviolet light) are combined and even reinforced, and the disadvantages are eliminated. Because of these properties, such a sealant and / or adhesive sealant composition can be widely used for fastening and jointing work, and in particular in the construction sector, and can be used, inter alia, on a wide variety of porous or non-porous surfaces such as concrete, mortar, brick, tile or plaster.
    By exposure to atmospheric humidity, reactive end groups of cross-linkers present on the silane-modified polymers are hydrolyzed. The ends obtained can then react with each other by a condensation reaction, so that a network is formed and the sealant or glue kit hardens.
    A problem with the known silane-modified polymers is the relatively large loss of volume after the application and curing of the silane-modified polymers. Shrinkage of silane-modified polymers during the curing process reduces and / or minimizes the tack and sealing ability of silane-modified polymers.
    BE2016 / 5898
    Another known problem in the prior art is the large amount of waste associated with the use of a sealant and / or adhesive sealant with a composition comprising silane-modified polymers, since the packaging material in the prior art is cylindrical plastic tubes to be.
    The present invention aims to solve at least some of the above-mentioned problems.
    SUMMARY
    For this purpose, the present invention provides in a first aspect a sealant sealant and / or adhesive sealant composition with silane-modified polymers according to claim 1. More particularly, the first aspect of the invention relates to a sealant and / or adhesive sealant composition with silane-modified polymers which it is particularly useful in the construction sector and can be applied inter alia on porous or non-porous surfaces such as concrete, mortar, brick, tiles or plaster, comprising:

    The inventors of the present invention have found that this sealant sealant and / or sealant sealant composition with silane-modified polymers comprises advantageous properties for use as a sealant or adhesive sealant for fastening and jointing work in the construction sector. This is evidenced, among other things, by the low weight loss and / or volume loss of the composition as determined according to ISO 10553, which indicates a limited shrinkage of the composition.
