Patent ID: 6878771

Claim:
A pigmented moisture-curing coating composition which, upon curing, forms a film having a matte finish comprising: about 50-85 percent of a pigmented dispersion comprising: about 47-60 percent of a pigmented slurry comprising an admixture of: about 10-40 percent of a solvent; about 10-40 percent of a water-containing pigment; and about 3-20 percent of synthetic silica; and about 0.1-2.0 percent of a tertiary amine catalyst; about 0.5-3.0 percent of a polyisocyanate admixed with the pigmented slurry and tertiary amine catalyst, said polyisocyanate being present in excess of an amount sufficient to essentially dehydrate the pigmented slurry; and about 2.0-20 percent of an organic polyol admixed with the pigmented slurry, polyisocyanate and tertiary amine to yield a pigmented paste including a urethane polyol reaction product having hydroxyl groups, said polyol being present in an amount sufficient to react with substantially all of the polyisocyanate, said pigmented paste forming a pigmented dispersion upon dispersion; and about 15-50 percent of an isocyanate prepolymer admixed with the pigmented dispersion, said isocyanate prepolymer being present in excess of an amount sufficient to react with all of the hydroxyl groups.
