Transparent liquid pigments for polyester, epoxy and vinyl ester resin. They tint the resin while still letting light through, which is what you want for casting, art resin, tinted skim coats and see-through laminates. Opaque pigment blocks light; these don't.

How much to add

These are strong. One drop per quart of resin gives a light tint; up to 1/4 oz per gallon gives a deep, dark transparent color. Add by the drop, mix fully, and check against light before adding more. Depth builds with every drop, so sneak up on it.

At these loadings there is no measurable effect on cure. Catalyze polyester and vinyl ester with MEKP as normal; mix epoxy at its standard ratio.

Four colors (blue, green, yellow, red) in sizes from 1 oz to 1 gallon. Need solid color instead? See our opaque liquid pigments in 14 marine colors.

How do I color resin or gelcoat with liquid pigment?

Stir the liquid pigment into the resin or gelcoat before you add the catalyst or hardener, mixing until the color is even with no streaks. Keep pigment to about 10% of the resin by weight at most, since too much pigment can stop the resin from curing fully. Our pigments work in polyester, epoxy, vinyl ester, and gelcoat. Add the MEKP or hardener last, then apply.

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.
