West System 422 Barrier Coat Additive. Additives for special coating properties Additives are blended with mixed epoxy to alter the physical properties of epoxy when used as a coating. Additives can be used to alter the color, abrasion resistance or moisture resistance of cured epoxy Coloring epoxy For colors other than white or gray, powdered pigments (tempera paint, colored tile grout, aniline dyes) and universal tinting pigment can be added to the epoxy mixture. Acrylic paste pigments (available from marine chandleries) are also used to tint the mixture, as long as they are specified for use with polyester or epoxy resin. 423 Graphite Powder will color the epoxy black or impart darker shades to colors. Generally, coloring agents can be added to the mixed epoxy up to 5% by volume with minimal effect on the cured epoxy's strength. Always make test samples to check for desired color and opaqueness and for proper cure. None of these coloring additives provide UV resistance to the cured epoxy, so limit their use to areas not exposed to sunlight unless additional UV protection is applied.
