Abstract
A non-slip composition for application to a ground surface where lighting conditions may be poor including a polymer epoxy having two parts of diglycidyl ether resin and one part aliphatic amine adduct modified with 30% AEP as a stabilizer. A phosphorescent pigment including zinc, sulfide, and copper may be mixed with the epoxy to provide luminescent characteristics thereto. During application, a clear aluminum oxide aggregate is spread across a layer of the applied epoxy prior to curing, thereby enhancing the light emitting properties of the phosphorescent pigment as well as providing non-slip characteristics to the exposed surface of the applied layer of epoxy.
