Abstract: The invention relates to a method for reducing water content of an epoxy or/and polyurethane paint dispersion to be prepared in a sealed and pressurized aerosol can which paint dispersion comprises, —free water of an amount W1, —organic solvent(s) of an amount W2,5-epoxy or/and polyurethane resin of an amount W3, —liquefied propellant of an amount W5, —ketone of an amount W6, —blocked hardener (hardener precursor) of the epoxy or/and polyurethane resin of an amount W4, wherein said blocked hardener compounds of said epoxy or/and 10 polyurethane resin is selected from the group comprising of an aldimine, an enamine, an imine, a Mannich base, a Schiff's base, an oxazolidine or a bisoxazol-idine, and mixtures thereof, —adjuvants, —water scavenger(s), —catalytic amount of a weak acid to shift equilibrium of reversible reaction (I) between the free water present in said dispersion and blocked hardener compounds of the epoxy or/and polyurethane resin back to formation of said initial epoxy or polyure-thane blocked hardener compounds and to prevent formation of the epoxy or/and polyurethane hardener amines: expoxy and/or polyurethane hardener+ketones catalyst expoxy and/or polyurethane+free water (amine) hardener precursor (1). The method comprises a step in which before providing organic solvent into the aerosol can its water content is reduced by admixing reactant with sulfonyl isocya-nate functionality as a water scavenger into said organic solvent.

Abstract: Filling device for filling an aerosol container with a liquid, such as paint, which device comprises a cup for the liquid for the aerosol container, which cup is provided with an injection opening at its bottom surface; a piston for pushing the liquid from the cup via the injection opening to the aerosol container; and a piston head that is adapted to be detachably fixed on the end of the piston to be in contact with the liquid in the cup when the liquid is transferred from the cup to the aerosol container, which piston head is in the form of a scraper in continuous contact with the side wall of the cup during the liquid transferring operation, wherein the detachable fixing of the piston head allows the piston head to be withdrawn together with the piston from the cup after the liquid transferring operation is done.
