    The main purpose of hardener epoxy-Diane resins is also used in the production of ion-exchange resins, additives and for other purposes. Epoxy resin ED-20 — a two-component resin. For its curing requires curing agents for epoxy resins (PEPA, THETA, etc.). When using the hardener of the brand PEPA (polyethylene polyamine), it takes from 5 to 30%, depending on the type of work, the average recommended ratio of 1:7. Into seven parts resin, one part hardener. A compound of resin and hardener must be carried out at a temperature not lower than 20°C. the gelling Time is approximately 1,5 hours, but full curing time is 24 hours.
