D.E.N. 439 is a general purpose, widely used epoxy novolac resin. It is recognized as a standardfor high temperature applications from which variations have been developed. It is useful in adhesives, structural laminates, coatings and castings for elevated temperature service. Laminates canbe made using D.E.N. 439 in combination with mica, synthetic glass-fiber or fiberglass reinforcement.
- Combines the thermal stability of a phenolic backbone with the reactivity and versatility of a bisphenol A epoxy resin
- Highly functional (±
- 3.8) epoxy novolac resin with improved reactivity
- The higher viscosity offers a means of obtaining good drape and limited tack in prepreg formulations.
