Description

D.E.N. 438L is a general purpose, widely used epoxy novolac resin. It is recognized as a standard for high temperature applications from which variations have been developed. D.E.N. 438L has multi-epoxy functionality (±3.6). These additional reactive sites produce tightly cross-linked cured systems. This makes D.E.N. 438L useful in adhesives, structural laminates, coatings and castings for elevated temperature service. The thermal stability of a phenolic backbone with the reactivity and versatility of a bisphenol A epoxy resin are combined in D.E.N. 438L Epoxy Novolac Resin. Laminates can be made using D.E.N. 438L Epoxy Novolac Resin in combination with mica, synthetic glass-fiber or fiberglass reinforcement.

Lower viscosity version of D.E.N. 438 epoxy novolac resin to allow higher solids and/or lower viscosity formulations.
