| titleOfInvention | To prevent the curing agent compound from forming from the curing agent precursor and to extend the shelf life of the dispersion |
| abstract | The present invention relates to a method for preventing the formation of a curing agent compound from a curing agent precursor in a sealed pressurized aerosol can comprising a paint forming dispersion, wherein the paint forming dispersion is formed after the sealing of the can, Epoxy and / or polyurethane-based resin, containing the epoxy and / or polyurethane resin curing agent precursor of amount W3, wherein the epoxy or urethane curing agent precursor is imine, enamine, Mannich base, Schiff base, oxazolidine, aldimine And mixtures thereof, wherein the paint forming dispersion contains amount W1 of free water, the amount W1 in the range of 1 to 10000 ppm, and the other paint before sealing the can. It is placed in the can with the dispersion forming chemical. In the above invention, The dispersion also contains a catalytic compound, preferably a weak acid, in order to prevent the formation of epoxy and / or polyurethane curing agent amines from said epoxy and / or polyurethane curing agent precursors, Whereby the catalyst compound shifts the equilibrium of the reversible reaction (2a) between the free water present in the dispersion and the epoxy and / or polyurethane curing agent precursor to return to the formation of the initial epoxy or polyurethane curing agent precursor: The reversible reaction 2a takes place during the total residence time of the dispersion in a sealed can. |
