Key Features
  • It is recognized as a standard for high temperature applications from which variations have been developed.
  • D.E.N.® 438 Resin has multi-epoxy functionality (±3.6).
  • These additional reactive sites produce tightly cross-linked cured systems.
  • This makes D.E.N.® 438 Epoxy Novolac Resin 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.® 438 Epoxy Novolac Resin.
  • Laminates can be made using D.E.N.® 438 Epoxy Novolac Resin in combination with mica, synthetic glass-fiber or fiberglass reinforcement.
  • Semi-solid epoxy novolac resin. Average functionality of 3.6.
