- D.E.N.® 438 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 has multiepoxy functionality (±3.6).
- These additional reactive sites produce tightly cross-linked cured systems.
- D.E.N.® 438-MK75 epoxy novolac resin solution 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.
