SMD Sunflash UV-Activated Polyester Resin (1 Gallon) The SMD SFR-GAL is a professional-grade polyester resin designed for rapid curing via ultraviolet light. It eliminates the need for chemical catalysts, allowing for extended work time indoors and a fast set time once exposed to UV rays. Key Features: 100% UV Activated: Sets in as little as 1 minute when exposed to direct sunlight. Zero Catalyst Required: No mixing of hardeners is needed; the resin is ready to use directly from the gallon container. Indefinite Pot Life: Will not harden while working indoors, preventing wasted resin and "stuck" brushes. High Saturation: Engineered for excellent penetration into fiberglass mat and cloth. Post-Cure Finish: Leaves no lingering chemical odor once fully cured.
