EPIFANES MONOURETHANE. Various colors. Years of testing and on-vessel experience have proven this unique finish to be the most advanced, highly engineered single-part formulation, based on urethane-alkyd resins available. It gives incredibly hard urethane abrasion and chemical resistance with outstanding gloss, durability, color retention and UV protection. This formulation was developed to provide the application ease of traditional enamel with the durability of a urethane resin base. It can be applied directly on thoroughly degreased and sanded fiberglass, one-component primers and topcoats, as well as on thoroughly sanded two-component polyurethane's.
