Universal Catalyst Hardener

Universal Catalyst is the standard hardening component for Poly-Glass 320 Resins, mixed at 10 oz resin to 5 oz catalyst (by volume) for an average 35 sq ft bathtub, then thinned with All Purpose Reducer for spraying. It is California 2020 VOC-compliant and formulated to deliver a hard, durable, long-lasting cure across the entire 320 topcoat family – one catalyst for every 320 colour and gloss level.
