Epoxy Color Code

Using colored electrical tape to identify similar part A and part B bottles of epoxy is a good way to avoid bad mixes. I use different colors for 5-minute, 15-minute, and 30-minute epoxy because the printed identification on the bottle often becomes unreadable. If you accidently mix 5-minute part A with 15-minute part B, the epoxy won’t cure. This means that you will have to separate the parts and really clean the surfaces before gluing...
