14.03.2016Epoxies are not cured with a catalyst, like polyester resins, but instead use a hardener (also called a curing agent). The hardener (part B) and the base resin (part A) co-react in an "addition reaction," according to a fixed ratio. Thus, it is critical to use the correct mix ratio of resin to hardener in order to ensure a complete reaction
