Abstract
An aerosol paint formulation capable of providing a high gloss pigmented finish comprises a propellant and a water-based concentrate which essentially contains water, a film-forming acrylic polymer and a lower monohydric alcohol.
Claims5
An aerosol composition having a pH of about 7.2 to about 10 and suitable for spray application to a substrate surface and air drying to a continuous film thereon which has high gloss and excellent durability including high flexibility retention and high gloss retention, said composition consists essentially of:
- (a) about 10 to about 30% by weight of at least one propellant,
- (b) about 15 to about 35% by weight of at least one aliphatic monohydric alcohol of the formula:
- R-OH wherein R is an unsubstituted straight or branched chain alkyl group, and containing 1 to 4 carbon atoms,
- (c) about 10 to about 45% by weight of water,
- (d) about 8 to about 25% by weight of an insoluble film forming acrylic polymer in particulate form suspended in said composition, said acrylic polymer consisting of a water-insoluble interpolymer of (A) units from at least one neutral free-radical polymerizable ester having a vinylidene group attached to the functional group, which ester by itself yields a soft linear polymer, (B) units from at least one polymerizable aromatic monovinylidene compound which by itself yields a hard polymer, and (C) units from at least one neutral polymerizable aliphatic monovinylidene compound substituted by a cyano group and which by itself yields a hard polymer,
- (e) up to about 3% by weight of at least one surfactant present in an amount at least sufficient to maintain solids suspended in the liquid phase,
- (f) 0 to about 15% by weight of a pigment,
- (g) 0 to about 5% by weight of a coalescing solvent,
- (h) 0 to about 1% by weight of a pH stabilizer,
- (i) 0 to about 2% by weight of an antifoam agent, and
- (j) 0 to about 2% by weight of a plasticizer.
