Using the epoxy resins Epon 828 (diglycidyl ether of bisphenol A) and DEN 438 (an epoxylated novalak) with chlorendie anhydride as the curing agent, a series of formulations were developed having a very wide range in the anhydride: resin ratio (40–160 phr). This range was made possible by the use of metal chelate catalysis. While these systems were not evaluated for fire retardancy, it is anticipated that they would exhibit this property dependent on their chlorine contents.
