Mix Ratio Calculator

Many materials, especially epoxies and tin-cure silicones, require a mix ratio by either weight or volume other than 1:1. Use this page to help determine how much of each material you will need to mix.

Fill in the mix ratio according to the instructions on the material you’re using. For example, Smooth-on’s EpoxAcoat is 5A:1B by volume (measured using measuring cups), or 100A:15B by weight (measured using an accurate scale, preferably digital).

Mix ratio according to instructions:

Part A:
Part B:

Fill in one of these three boxes and click the button below. The other two will be calculated for you.
