ARALDITE^® EPN 1179 and ARALDITE^® EPN 1180 epoxy phenol novolac resins contain more than two epoxy groups per molecule and can be described as multifunctional epoxy resins. Due to the increased epoxy functionality, EPN resins provide a high cross-link density when properly cured. Systems based on ARALDITE EPN 1179 epoxy phenol novolac resins or ARALDITE EPN 1180 epoxy phenol novolac resins possess better chemical and high temperature resistance than those based on standard bisphenol A epoxy resins.

EPN resins are recommended for high-performance applications requiring good chemical and solvent resistance. When combined with suitable curing agents (i.e. polyamines, novolacs and anhydrides), they can be used as the sole resins, or in blends with bisphenol A and F epoxy resins, to upgrade the performance of the latter. EPN Resins can also be used in: two-component, room-temperature cure, forced-cure or heat-cure systems, solvent-containing, high solids, solvent-free or waterborne coatings.

The heat-curable systems produce the ultimate performance (chemical and thermal resistance). This is due to more complete reactions with the curing agents at higher temperatures, and overcoming the stearic hindrance of the multifunctional epoxy resins.
