| titleOfInvention | Method for preventing formation of hardener compounds from hardener precursors and extending shelf life of dispersions |
| abstract | The present invention relates to a method for preventing the formation of a hardener compound from a hardener precursor in a sealed and pressurized aerosol can, comprising forming a dispersion of a coating, after sealing the can, the dispersion contains a liquefied propellant, an amount of W1 Epoxy or/and polyurethane resins, hardener precursors of said epoxy or/and polyurethane resins in amount W3, wherein said epoxy or urethane hardener precursors are selected from the group consisting of imines, enamines, mannites The group of Nisch bases, Schiff bases, oxazolidines, aldimines, and mixtures thereof, free water in amount W1, amount W1 in the range of 1-10000 ppm, and prior to sealing the canister, free water and said other The chemicals that form the coating dispersion are introduced into the tank together. In said invention, the dispersion also contains a catalytic compound, preferably a weak acid, to prevent the formation of epoxy or/and polyurethane hardener amines from the epoxy or/and polyurethane hardener precursor, wherein the catalytic compound alters the presence of The reversible reaction (2a) between the free water in the dispersion and the epoxy or/and polyurethane hardener precursor equilibrates back to form the initial epoxy or polyurethane hardener precursor: (2a), wherein the reversible reaction (2a) occurs during the entire residence time of the dispersion in the sealed tank. |
