Liquid Blue Dye 505 - for WEST SYSTEM Epoxy Resin (125G)

Product Description

Pigment Blue 505 is an epoxy-based liquid colorant used to tint the epoxy mixture gray, providing a uniform gray colour base for the final finishing system. Coloured surfaces also tend to highlight defects and imperfections. Cured pigmented epoxy surfaces are not a final finish surface, but require additional paint or UV filter coating for ultraviolet protection.

Usage Instructions

Add to the mixed resin/hardener at the rate of approximately one teaspoon of pigment to 8 fl oz of epoxy. More pigment will increase the opacity and viscosity of the mixture. A 4 fl oz bottle will tint approximately 1.5 gal of epoxy.

Applications

Adding a colouring agent to WEST SYSTEM® Epoxy is frequently done to make coloured castings, highlight an epoxy-coated surface, act as a coloured base coat for paint, etc. Most powdered pigments are satisfactory, as are acrylic paste pigments and universal tinting pigment.

Recommendations

Adding pigment to epoxy should, like everything in life, be done in moderation. Without exception, adding pigment to WEST SYSTEM Epoxy will weaken the cured mixture to some degree. Because of this, we suggest you use very small amounts of pigment, about 5% by weight. As a result, thin films of coloured epoxy are somewhat transparent. It usually requires several coats to make the film opaque.

Available Colors

WEST SYSTEM pigments are available in three colours, white, black and grey. We suspend the pigments in an epoxy resin base which allows them to blend thoroughly into the epoxy to make very uniform colours. Because the pigment has an epoxy resin base, it is important not to add more than the recommended amount. Adding an excessive amount of pigment to the epoxy could alter the resin/hardener ratio, compromising cured epoxy performance.

Tinted Epoxy Putty

If you need to make a tinted epoxy putty for filling defects, mix WEST SYSTEM epoxy with 406 Colloidal Silica Filler to make the putty. The addition of 406 to the epoxy results in an easily coloured, smooth, off-white paste that can be tinted with one of the pigments.

UV Resistance

Epoxy, tinted or clear, does not have good UV light resistance. An epoxy coating exposed to UV will yellow, become opaque, and eventually flake off. This process takes a while and if the object you are coating has limited exposure to sunlight, a coloured epoxy coating will hold up for years.
