West Systems 5038 503 Gray Epoxy Pigment 4 oz Bottle

West Systems 503 Gray Epoxy Pigment is a liquid colorant designed to tint epoxy mixtures and provide an even, neutral gray base for final finish systems. This pigment integrates seamlessly into mixed resin and hardener, creating a uniform colored surface that helps highlight surface flaws and imperfections during preparation and finishing work.

Key Features:

• Liquid epoxy-based pigment for consistent, even color distribution
• Neutral gray tone ideal for underlayment and surface preparation
• Simple mixing ratio: approximately 1 teaspoon of pigment per 8 fl. oz. of mixed epoxy
• One 4 fl. oz. bottle tints approximately 1.5 gallons of epoxy
• Highlights surface imperfections for easier detection and correction
• Compatible with West Systems epoxy resin and hardener systems

Application Notes:

Add pigment to the mixed resin/hardener combination and stir thoroughly for even color distribution. The resulting gray surface provides an excellent base for topcoats and finishing systems. Note that pigmented epoxy will degrade under prolonged sunlight exposure and is not intended as an exterior finish coat—always apply a UV-resistant topcoat for outdoor applications.

Ideal for marine applications, composite layups, and repair work where visual detection of surface preparation quality is important.
