Enter the amount of epoxy resin and the recommended pigment to epoxy ratio into the calculator to determine the amount of epoxy pigment needed. This calculator can also evaluate any of the variables given the others are known.

Epoxy Pigment Formula

The following formula can be used to calculate the amount of epoxy and pigment needed for a project.

EP = (A * r) / 100

Variables:

  • EP is the amount of epoxy pigment needed (grams)
  • A is the amount of epoxy resin (grams)
  • r is the recommended pigment to epoxy ratio (%)

To calculate the amount of epoxy pigment needed, multiply the amount of epoxy resin by the recommended pigment-to-epoxy ratio. Then divide the result by 100 to convert the percentage to a decimal. This will give you the amount of pigment needed in grams.

What is an Epoxy Pigment?

An epoxy pigment is a type of colorant used specifically for epoxy resins. It is used to add color and aesthetic appeal to epoxy projects, such as countertops, floors, jewelry, and other crafts. These pigments are available in a wide range of colors and can be mixed to create custom shades. They are typically sold in powder or liquid form and are mixed into the epoxy resin before it is applied. The pigment does not affect the performance or durability of the epoxy, it simply adds color.

How to Calculate Epoxy Pigment?

The following steps outline how to calculate the amount of epoxy pigment needed using the formula EP = (A * r) / 100.


  1. First, determine the amount of epoxy resin (A) in grams.
  2. Next, determine the recommended pigment to epoxy ratio (r) in percentage.
  3. Next, use the formula EP = (A * r) / 100 to calculate the amount of epoxy pigment needed in grams.
  4. Finally, calculate the result.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem:

Use the following variables as an example problem to test your knowledge.

Amount of epoxy resin (A) = 200 grams

Recommended pigment to epoxy ratio (r) = 5%
