Opaque liquid pigment for coloring polyester resin, gelcoat and epoxy all the way through the laminate. Stir it in until no streaks are left and the color goes wherever the resin goes, through every ply rather than sitting on the surface. Each color comes in 1 oz bottles up to gallons.
Loading for solid color
| Resin | Pigment for full opacity |
|---|---|
| 1 quart | 1 fl oz |
| 1 gallon | 4 fl oz |
Treat that as the ceiling as well as the target: going past 1 fl oz per quart can soften the cure. For a light tint, start with a few drops per quart and build up. By weight the dose depends on the color, because the pigments are not the same density: about 3% for carbon black, 5 to 6% for titanium white and 6.5 to 8% for maize yellow.
Resin by resin
- Polyester resin and gelcoat: mix the pigment in first, then add MEKP as usual. At these loadings the gel time does not shift enough to plan around.
- Epoxy: stir it into the mixed resin.
- Urethanes: some systems take it and some do not, so test a small batch.
Pigmented laminating resin is not a UV-stable finish on its own. For color that lasts in the sun, tint gelcoat and use that as the final coat. Casting or art work that needs see-through color takes our transparent liquid pigments; opaque pigment blocks the light at any useful loading. More finish-coat options are under gelcoats and additives.

Specifications
For use in polyester resins, gelcoats and epoxy resins to give a solid colored appearance.
Recommended ratios for full opaque color:
- 1 quart resin: 1 oz (fluid) pigment
- 1 gallon resin: 4 oz (fluid) pigment
- Keep total pigment under about 5% by weight or cure can suffer
Polyester and gelcoat: tint first, then catalyze with MEKP as normal. Epoxy: add to mixed resin and stir until streak-free. Pigmented resin is not a UV-stable finish on its own; tint gelcoat for exterior color.

How do I color resin or gelcoat with liquid pigment?
Stir opaque liquid pigment into polyester resin or gelcoat before you add the MEKP, or into epoxy after it is mixed with hardener, until no streaks remain. Use about 1 fl oz per quart (4 fl oz per gallon) for solid color and treat that as the ceiling, since more can soften the cure. For a light tint, start with a few drops per quart.
What's the difference between opaque and transparent liquid pigment?
Opaque pigments like carbon black and titanium white fully hide what is under them and give a solid color, which is what you want for gelcoat and most colored laminates. Transparent pigments tint the resin while still letting light pass through, so the weave or what is beneath stays visible, which suits clear casting, tinted coatings, and decorative work. Choose opaque for solid color and transparent for a see-through tint.
What's the difference between mica powder and liquid pigment?
Liquid pigment is a concentrated colorant that gives solid, even color, so it is the choice for matching gelcoat or coloring a laminate. Mica powder is an ultra-fine pearlescent powder that adds a metallic shimmer and depth instead of flat color, which suits clear casting, resin art, tumblers, and decorative finishes. Both work in epoxy, polyester, vinyl ester, and gelcoat. Use liquid pigment for true color and mica for sparkle and pearl effects.
