Key Features
  • D.E.N.® 438-A85 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.® 438-A85 Resin has multi-epoxy functionality (± 3.6).
  • These additional reactive sites produce tightly cross-linked cured systems.
  • D.E.N.® 438-A85 Epoxy Novolac Resin is used alone or in combination with bisphenol A based epoxy resins in solution formulations where ease of mixing and processing is required. The thermal stability offered by epoxy novolac resins is a widely accepted asset in pre-preg manufacture for electrical laminates where they improve the resistance to hot solder as well as elevated temperature service.
  • They are also used in coating applications where an increased corrosion/chemical resistance is desired.
