Have you ever wondered how to properly mix a two part epoxy? First here's a little background. Two component epoxies are available in a wide variety of mix ratios. They are commonly mixed by weight, but certain systems can be mixed by volume.

Using a 1 to 1 mix ratio by weight for this demonstration, let's take 100 grams from the container with Part A, and 100 grams from the container with Part B and pour them into a contamination free mixing vessel. Part A is colored yellow, and Part B blue. (Our epoxies are available in a wide range of colors.) No matter the viscosity, mixing should be done in a slow, methodical manner to avoid air entrapment. As the two parts are mixed together, the color is turning green. Once the color is uniform, and there are no streaks, the epoxy is ready to be applied.

What happens if the two components are not mixed thoroughly, or if there is a significant error in the mix ratio? Well, then the epoxy may cure soft and not develop all the required physical properties. When the epoxy has a short pot life, we recommend mixing only minimal amounts in a shallow mixing vessel. When mixing a system with a more challenging mix ratio, you may want to consider using a gun applicator or divider pouch where Parts A and B come already pre-measured.
