Abstract
The present invention is directed to a sprayable coating composition having improved water resistance, improved mar resistance and generally improved physical properties, and a method of using such a coating. The sprayable coating composition comprises a resin system comprising from about 30 to about 96 weight percent of a resin component, from about 1 to about 30 weight percent of a multifunctional acrylate component, and from about 1 to about 15 weight percent of a monofunctional acrylate component; and a catalyst component. The resin system is blended with the catalyst component, either internally or externally of a spray nozzle, and the resultant sprayable coating composition is sprayed onto a substrate. The resulting cured coating provides a surface which is water resistant, is mar resistant, and has generally improved physical properties.
