Epoxy must be thoroughly mixed and then degassed to remove bubbles. (In the production process, you don’t want to dispense any bubbles inside the ferrule.)

You may have heard the advice to mix epoxy based on time, for example, 1 minute of mixing or 90 seconds of mixing. But when mixing manually, different users may mix at different rates – that is, one person may stir more quickly than another, or if roll-mixing a bi-pack one person may roll faster than another.

For epoxy bi-pack mixing, using a roller or the edge of a table, we recommend using a counting-based process rather than a time-based process. Usually, 20-25 uniform passes using a consistent mixing rhythm should be sufficient. The goal is to thoroughly blend Part A and Part B with minimal bubbles. Bubbles will appear in properly mixed epoxy. If you mix too vigorously, you can trap more air and introduce more bubbles, and this may add time to your degassing process.
