What is conversion varnish paint?
Conversion Varnish is a chemical-cured, fast-drying finish that consists of 2 parts: the finish and an acid catalyst that’s added just before spraying. The catalyst creates a chemical reaction (cross-linking) in conjunction with added heat-curing that creates the hardest, most durable finish available on the market.
