Curing agents that give the optimum in elevated temperature properties for epoxy novolacs are those with good high temperature performance such as aromatic amines, catalytic curing agents, phenolics and some anhydrides. When cured with polyamide or aliphatic polyamines and their adducts, epoxy novolac resins show improvement over bisphenol A-based epoxies, but the critical performance of each cure is limited by the performance of the curing agent.

ARALDITE® EPN 1139 Resin is supplied in 525-pound steel drums. The product should be stored in a dry place, in the sealed original containers, at temperatures between 2°C and 40°C. Under these storage conditions the shelf life is 2 years (from date of manufacture). The product should not be exposed to direct sunlight.
