Epoxy Resins & Hardeners

Hardener Cure Speed Each WEST SYSTEM Epoxy hardener has an ideal temperature cure range. At any given temperature, each epoxy resin/hardener combination will go through the same cure stages but at different rates of speed. Base your hardener selection on the amount of working time you’ll need for the job you’ll be doing at the temperature conditions you’ll be working under. The hardener selection guide and epoxy hardener container labels describe hardener pot lives and cure times. The data we provide pot life is based on 100 grams or 4 pump strokes each of resin and hardener using our 300 Mini Pumps. If you are using a larger amount of epoxy or a different size of mixing pot the length of pot life can vary. To increase the pot life of a cup of mixed epoxy, spread it over a larger surface area, work in a cooler environment, or mix multiple, smaller batches as you go.
