A coating composition is provided. The composition comprises as component I, a) a polyaspartic acid ester comprising the reaction product of one more diamines, one or more difunctional acrylate-containing compounds and one or more maleic/fumaric acid esters; b) at least one moisture scavenger; c) at least one deaerator; d) at least one plasticizer; and e) optionally additives; and as component II, one or more polyisocyanates. Methods of making and applying the composition to a substrate are also provided. The coating is particularly suitable for use as a gel coat.

The present invention is directed to a composition curable by radiation having a wavelength of 300 nm or more, a method of producing a coated substrate using such composition and the coated product so-produced. More particularly, the composition of the present invention comprises A) from about 1 to about 99% by weight of an unsaturated polymer or oligomer, B) from about 1 to about 99% by weight of an unsaturated epoxy acrylate, C) one or more photoinitiators, and, optionally, D) one or more solvents.
