<p>Described is a liquid sprayable epoxy composition comprising a liquid epoxy resin, an effective reinforcing amount of a fiber, an elastomeric component and an amine containing epoxy curing agent capable of curing the composition at equal or greater than 40 DEG F. temperatures wherein the cured product is light stable and has a hardness on the Shore D scale. Further described is a method of forming in situ a cured product such as a truck bed liner by spraying, brushing or troweling the epoxy composition onto the substrate such as the trunk bed, curing and forming the product on the substrate at a temperature of at least 40 DEG F. temperature. The ratio of epoxy reactive groups to amine reactive groups ranges from 0.9 to 1.1:1. Further described is a technique of modifying the coating coefficient of friction by sand embedment between the induction period and cure set time of applied epoxy composition.</p> |
