摘要： A solvent system is provided, which enables increased amount of exact color tone recipes even when using with currently known dispensing machines having a minimum dispensing limit of 0.01-0.02 ml of a color paste component. The system enables a capability of tinting paints in a tone-accurate manner even into aerosol paint cans of small filling volume. The system provides a capability of radically reducing the amount of various ready-to-use aerosol paints and aerosol base paints stocked by a storekeeper. The disclosure provides an aerosol paint for tinting, as well as a tinted aerosol paint which is suitable for use in a process of mechanized tinting, and by which a good paint coverage on a painted surface is achieved.

摘要： A water-based paint composition for pressurized, sealed aerosol can, and method to make same is disclosed. The composition contains up to 24% w/w propellant gas dimethyl ether (DME); up to 76% w/w coating material, consisting of 65-95% w/w nonvolatile content and 5-35% w/w volatile content. The volatile content contains 0-100% w/w water and additives, co-solvents and dispersing agents comprising altogether of 0-6% w/w volatile liquids, having 0-10% w/w, preferably 0-5% w/w volatile organic compounds (VOC) provided that the aggregate amount of DME and the VOC in volatile liquids remains below about 24% w/w calculated as DME, and nonvolatile content comprises 0-30% w/w color pigments and optional fillers, 45-99% w/w polyurethane modified alkyd resin or alkyd resin and additives up to 9% w/w. The resin is present as emulsified dispersion in water miscible preferably up to 5% w/w solvent comprising water and DME.

摘要： The invention relates to a water based paint composition to be used in a pressurized and sealed aerosol can and which composition contains A) up to 24% w/w of propellant gas which is dimethyl ether (DME); B) up to 76% w/w of coating material, consisting nonvolatile content in the range of 65-95% w/w and volatile content in the range of 5-35% w/w; —which volatile content contains water up to 0-100% w/w and additives, co-solvents and dispersing agents which comprise altogether of 0-9% w/w of volatile liquids, having 0-10% w/w preferably less than 5% w/w of volatile organic compounds (VOC) provided that the aggregate amount of dimethyl ether (DME) and the volatile organic compounds (VOC) in volatile liquids is such that VOC concentration is below 186 g/l (responding about 24% w/w, calculated as DME). In the present invention the nonvolatile content comprises color pigments and possible fillers in the range of 0-30% w/w, polyurethane modified alkyd resin or alkyd resin in the range of 25-99% w/w preferably in the range of 35-90% w/w and additives up to 9% w/w, which resin is present as an emulsified dispersion in water miscible solvent comprising water and dimethyl ether (DME).

摘要： A method is disclosed for preventing hardener compounds to be formed from hardener precursors in a sealed and pressurized aerosol can. This includes a paint forming dispersion containing after sealing the can a liquefied propellant, epoxy or/and polyurethane resins amount W1, hardener precursor of the epoxy or/and polyurethane resins amount W3, where the epoxy or urethane hardener precursors are selected from a group including an imine, an enamine, a Mannich base, a Schiff's base, an oxazolidine, an aldimine and mixtures thereof, free water of amount W1 in a range of 1-10000 ppm, and brought into the can alongside with the other paint dispersion forming chemicals before sealing the can. A catalytic compound prevents formation of the epoxy or/and polyurethane hardener amines from the epoxy or/and polyurethane hardener precursors:
