TotalBoat UV Cure Clear Resin is not an epoxy product. It's a one-component acrylic urethane resin that cures under UV light, instead of curing at room temperature, as epoxy does. There's nothing to measure or mix, just pour the UV resin into molds and expose to a UV light source, such as the sun, a UV lamp, or a UV flashlight. UV Cure Resin also cures in minutes; epoxy can take hours or days to cure, depending on the epoxy system and the ambient temperature and humidity conditions.
