D.E.N.® 425

D.E.N.® 425 is a liquid reaction product of epichlorohydrin and phenol-formaldehyde novolac. D.E.N.® 425 Epoxy Novolac Resin is an epoxidized phenolic resin of higher functionality than standard bisphenol Abased liquid epoxy resins. Epoxy novolac resins combine, in one molecule, the thermal stability of a phenolic backbone with the reactivity and versatility of an epoxy. They are distinguished by particular good thermal stability, mechanical strength and resistance against chemicals. They find ready acceptance for lining pipelines, storage tanks and pumps. D.E.N.® 425 Epoxy Novolac Resin has been developed to fill the gap between the two functional standard bisphenol F based liquid epoxy resins and the high viscous epoxy novolac resins. It has a viscosity similar to a standard bisphenol A based liquid epoxy resin. The multi-functionality, ± 2.5 epoxy groups per mole, of D.E.N.® 425 Epoxy Novolac Resin produces a more tightly cross-linked cured system than bisphenol A based liquid epoxy resins having improved high temperature performance and improved resistance against various chemical.
