ARALDITE EPN 9880 Resin contains 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 crosslink density when properly cured. Systems based on ARALDITE EPN 9880 resin 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 excellent 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 be used in two-component room temperature cure, forced cure or heat cure systems. Solvent-containing, high solids, solvent-free or waterborne coatings can be formulated. 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 steric hindrance of the multifunctional epoxy resins.

The fields of application are determined by the choice of the curing agent. Among the more

common applications are industrial coatings for new construction and maintenance of:
