Polyester UV Catalyst
UV Catalyst is a powder mixed with polyester resin for UV (sunlight) curing. Photo-initiators absorb UV energy from the light source, setting in motion a chemical reaction that quickly converts liquid resin into it's solid form. Suggested 6.6 grams of UV Powder per gallon of resin.
33 Gram quantity is enough for 5 gallons of resin.
363 Gram quantity is enough for a 55 gallon drum of resin.
