Suggested 7cc of UV Powder per gallon of resin, adding more can result in faster cure but will result in a greenish-yellow final cured resin color. Thick laminates over 1/4" thick, pigment or logo laminates that may disrupt UV rays from fully penetrating the laminate may result in uncured areas. We suggest doing your own sample testing.The UV curing process requires a light source which directs UV or visible light onto the formulated product. Photoinitiators absorb the UV energy from the light source, setting in motion a chemical reaction that quickly, in fractions of a second, converts the liquid formulation into a solid, cured film. Methyl ethyl ketone peroxide also known as MEKP, catalyst or hardener, is a chemical that is added to polyester and vinyl resins to initiate a cured product. When MEKP is mixed with the resin, the resulting chemical reaction causes heat to build up and cure or harden the polyester resin. MEKP is required with all polyester resins, gel coats and vinyl ester resin.
