flake phenolic novolac resins for use as curing agents for epoxy resins in molding applications. These resins are useful as co-reactants or hardeners for epoxy resins to produce thermoset systems with high-quality, "engineering plastics" properties. The phenolic novolac resins used are non-heat reactive materials by themselves, but have phenolic-OH groups that react with epoxy groups. This base catalyzed reaction produces a crosslinked polyether structure that is highly resistant to chemicals and heat and provides a good moisture-vapor barrier. Since the curing mechanism does not produce by-products, thick sections may be obtained without voids and stresses and with low shrinkage. These properties are advantageous in applications such as coatings.
