<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 °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 truck bed, curing and forming the product on the substrate at a temperature of at least 40 °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 coatings coefficient of friction by sand embedment between the induction period and cure set time of applied epoxy composition.</p> |
