Pigments

AMT Composites stocks a small colour range of epoxy and polyester pigments. These are often used to colour resins to ensure full coverage when applying over a large surface, or to indicate which layer is being sanded into. Typically the maximum pigment loading is 5% by weight. When using epoxy pigments in a resin base, the pigment should be added to the resin, then the required hardener be added based on the resin plus pigment mass.
