Enter the total amount of resin (parts) and the total amount of hardener (parts) into the Epoxy Mix Ratio Calculator. The calculator will evaluate and display the Epoxy Mix Ratio.

Epoxy Mix Ratio Formula

The following formula is used to calculate the Epoxy Mix Ratio.

EMR =  R/H
• Where EMR is the Epoxy Mix Ratio (resin:hardener)
• R is the total amount of resin (parts)
• H is the total amount of hardener (parts)

To calculate the epoxy mix ratio, divide the amount of resin by the amount of hardener.

How to Calculate Epoxy Mix Ratio?

The following example problems outline how to calculate Epoxy Mix Ratio.

Example Problem #1:

1. First, determine the total amount of resin (parts).
• The total amount of resin (parts) is given as: 4.
2. Next, determine the total amount of hardener (parts).
• The total amount of hardener (parts) is provided as: 2.
3. Finally, calculate the Epoxy Mix Ratio using the equation above:

EMR =  R/H

The values given above are inserted into the equation below and the solution is calculated:

EMR =  4/2 = 2:1 (resin:hardener)

Example Problem #2:

For this problem, the variables required are provided below:

total amount of resin (parts) = 6

total amount of hardener (parts) = 3
