Polyester Colour Pigments are added to resins and gelcoats to provide a deep uniform colour. The pigment dispersion resin is a non-reactive resin and can act as a plasticizer so no more should be added than is needed.

Dark colours require 5-7% addition and never more than 10% should be added. The pigment paste should be mixed into the resin or gelcoat well, preferably with a mechanical mixer, and then stirred immediately before use.
