- Key Features
- D.E.N.® 439 Epoxy Novolac Resin 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.® 439 Resin has multi-epoxy functionality (±3.8).
- These additional reactive sites produce tightly cross-linked cured systems.
- D.E.N.® 439 Epoxy Novolac Resin is 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.® 439 Epoxy Novolac Resin.
- Laminates can be made using D.E.N.® 439 Resin in combination with mica, synthetic glass-fiber or fiberglass reinforcement.
