Abstract
The present invention provides a coating composition comprising: 1% to 99% of a blend of two or more aspartic ester functional amines; 20% to 70% of an acrylate-containing compound; 0.01% to 5% of an alkyl carbodiimide; 0.1% to 5% of a photoinitiator; and 20% to 70% of one or more polyisocyanates, wherein the composition has reduced discoloration compared to the composition without the alkyl carbodiimide. The ready-to-apply coating produced from this composition may find use on substrates such as countertops and floors.
