Mixing Pigment Colors Into Gelcoat, Epoxy, Or Polyester Resin

Using Pigment For Coloring

Our pigment is compatible with all types of resins and epoxies. However, when the pigment is mixed with a resin base that already contains a coloring agent such as white gelcoat, the pigment dye will be diluted. An example, mixing white paint with a black pigment will result in a gray color. 

If you would like to create solid colors using pigment, it is best to use a neutral or clear based resin to get the closest color match.

An example, mixing black pigment with a clear epoxy will result in a black epoxy. The same effect happens when mixing black pigment with neutral gelcoat. You will get black gelcoat. 

Users should be aware that adding too much pigment to a resin base can be harmful to the strength characteristics of the resin itself. The recommended mix ratio is 1-2 ounces of pigment to 32 ounces of resin or epoxy.

Maximizing Mixing Time

Most resins contain two parts, Side A and Side B. Once the two components are combined, Your working time will start. Consult your user instructions to see what the pot life of your product is. To maximize your mixing time, add the coloring pigment to the batch before combining Side A and Side B together. If you decide to add the pigment in after you blend both sides of the resin together, you will have less time to work with the resin before it starts to harden.
