Sand able after 15 min IR drying Example 7 General example for preparing a liquid intermediate product for an aerosol formu- lation (paint dispersion) Removing the excess amount of water prior adding liquid mixture into an aerosol can is preferably done in following way: Water content of solvent(s) and propellant is 500-6000 ppm. At least the moisture present in solvent should be reacted away The water is reacted away by addition — of sulfonyl isocyanate. For example, 12-24 gram of p-toluenesulfonyl isocyanate can react 1 gram of water away. The rest products of this moisture removing reac- tion is COz2and an inert sulfonamide. Tests had showed that when reacting 10000 ppm of water with sulfonyl-isocyanate the reaction product sulfonamide do not disturb even with high concentrations the film forming process and clear varnish can be prepared. © Mixing order and principles.O
    N — The necessary ketone containing solvents are mixed together for forming solvent © system. In a case paint dispersion which will give semi-gloss or matt paint surface - (end product) is to be prepared, the necessary matting agents (primer or filler) are = 25 — dispersed into the solvent system using high shire mixing. The water content of 5 this mixture containing solvent system and possible matting agents is determined 3 by Karl Fisher titration. Based on the determined water content of mixture the 5 amount of sulfonyl-isocyanate is calculated and added to the mixture.
    N The reaction between sulfonyl-isocyanate with water present in solvent system and possible mattening agents is ready within approximately 15 minutes.
    Again, a sample is taken and the water content or absent of this solvent system and possible mattening agents is again determined by Karl Fisher titration. If the water content is below 50 ppm the rest of raw materials for making paint, primer or clear coat can be added into said mixture of solvent system and possible matten- ing agents to make a liquid mixture by stirring gently. Due to the fact the liquid mixture to be sealed into an aerosol can is prepared un- der atmospheric conditions, the following safety net is built into the liquid mixture. The safety is based on the Shiff's base principle that an amine in the presence of a ketone will react to a ketimine/imine in the presence of a catalytic presence of a — weak acid. Therefore, acetone and MEK may be used as ketone containing sol- vents. All blocked hardeners will all form an amine in presence of water and in the case of aldimine and oxazolidine blocked hardener will form and amine and a pol- yol in the presence of water. To avoid the forming of epoxy/polyurethane hardening amines catalytic amount of — weak acid (pKa for example 3,5—6) is also added into liquid mixture, to create cir- cumstances for the forming of Shiff's bases. When liquid mixture is filled into an aerosol can weak acid will continuously prevent epoxy resin or/and polyurethane resin hardening compounds. Test have shown that using this principle paint dis- persion in the aerosol will be stable of a period of at least 3 years. The threshold value of the water content in the filled product is app. 700-1000 ppm. 00O
