Type: UV Photo-Initiator
Price: 5.00 - 95.00 (3 variants)

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 luxury 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.
