Very high quality pigment for polyester resin. Pigment paste are made the very highest quality with pigments triple milled to reduce them to the finest particle size. Smaller particles means more vibrant colours from less pigment, improving the appearance of pigmented parts whilst minimising the performance reduction of the resin caused by pigmentation. Pigment paste should always be used when pigmenting polyester or epoxy rather than pigment powder because the rigorous milling and mixing process during manufacture ensures that the tiny pigment particles are fully dispersed into a small amount of carrier polyester, getting the very most from their colour. When a paste is then added to the bulk of the polyester it blends in easily, ensuring that the pigment is thoroughly mixed through the resin (rather than staying in lumps). Because the dispersion is actually a mix of resin and pigment already, it is essential that the correct dispersion type is used to pigment each specific resin type. For example, polyester should only ever be pigmented using polyester dispersion pigment. Use to add solid colour to polyester laminating resin, polyester/epoxy gelcoat, epoxy electrical potting resin and polyester casting resin. A pigment ratio of 5-10% should be sufficient to add solid opaque colour in most applications.
