  • Acrylate-modified aspartates and gel coat compositions made therefrom
    Patent number: 8178204
    Abstract: 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.

  • UV-curable waterborne polyurethane dispersions for soft touch coatings
    Patent number: 7396875
    Abstract: The present invention is directed to a waterborne, UV-curable polyurethane emulsion and the use thereof in producing soft touch coatings. The emulsion is prepared by a) reacting specified hydroxy-functional components with di- and/or polyisocyanates, b) forming a dispersion of the resultant product with water and reacting the dispersion with amine functional materials.
