Curing composition for acrylic polyol coatings and coating produced therefrom

A two package coating composition which, when the two packages are combined, forms a fast cure coating, comprising

• a first package comprising an acrylic polyol;
• and
• a second package comprising a curing composition comprising:
• a) from about 20 to about 70 percent of an aliphatic polyisocyanate free from urethane groups;
• b) from about 20 to about 70 percent of an aliphatic polyisocyanate prepolymer which is the reaction product of a polyisocyanate with a polyol and contains urethane groups;
• c) from about 0.01 to about 5.0 percent of an ultraviolet light stabilizer;
• d) from about 0.25 to about 5.0 percent of a metal catalyst, the percentages of (a) to (d) based on the total weight of resin solids of the curing composition;
• and
• e) from about 20 to about 70 percent of an organic diluent, the percentage based on the total weight of resin solids and diluent of the curing composition.
