Take control of your cure time with our Polyester UV Catalyst. This high-potency powder allows you to convert standard polyester resin into a UV-activated system, giving you the lu xury of "infinite work time" until you're ready to set the resin in the sun. This additive utilizes advanced photo-initiators that absorb UV energy from sunlight or specialized UV lamps. Once exposed, the powder triggers a rapid chemical reaction, converting your liquid resin into a solid, hard finish in a matter of minutes. It is the perfect solution for garage builders who want to pull perfect laps without the stress of a chemical kick. Mixing Instructions: Suggested Ratio: 7 grams of UV Catalyst powder per 1 Gallon of resin. Compatibility: Designed for use with all standard polyester laminating and sanding resins. Key Benefits: Infinite Pot Life: Resin stays liquid indoors, allowing for stress-free laminations. Instant Cure: Hardens in 1–3 minutes when moved into direct sunlight. Cost Effective: A small amount of powder converts an entire gallon of standard resin. Pro Tip: For the best results, mix the powder into a small amount of resin first to create a "concentrate" and ensure there are no clumps, then stir that concentrate into your full gallon. Show more
