Abstract
A method for producing an in-mold coated plastic article having an adherent coating wherein the coating composition has improved surface coverage properties and a fast cure rate. The coating composition contains (a) a first component comprising at least one polyol having at least 4 hydroxyl groups and a viscosity at room temperature of 6000 cps or less; and (b) a second component comprising a solvent-free isocyanate prepolymer. The viscosity of the coating composition is 15000 cps or less at room temperature.
