A clear, viscous non-yellowing UV-cure aliphatic urethane designed to form thick, domed coatings on wood, metal or most any plastic. Cure response is in seconds upon irradiation by sunlight or artificial UV light source such as our H.O. flashlight - torch @ 385nm. The resulting polymer has good elongation (flex) yet with a very hard surface. This is a tough, highly abrasion-resistant resin. Curing is tackfree in less than 3 minutes. This resin requires strong sunlight or our H.O. flashlight torch to cure.
