Our colour pigments are pastes for tinting polyester, vinyl ester, and epoxy resins, and polyurethane foam. Our primary colours can be blended to any shade or hue. Keep an assortment of pigments on hand for colour matching repairs or blending your own custom colour. Stir or shake colour pigment well before using. Use small amounts of colourant to tint base. Mix thoroughly after each addition. Add or mix colourant to one quart resin/gelcoat. Test on a piece of scrap material before continuing project. ALWAYS MIX COLOUR PIGMENT WITH RESIN/GELCOAT BEFORE ADDING HARDENER OR CURING AGENT.
