Features & Benefits

Key Features
  • D.E.N.® 431 Epoxy Novolac Resin combines in one molecule the thermal stability of a phenolic backbone with the reactivity and versatility of an epoxy.
  • D.E.N.® 431 Epoxy Novolac Resin has multi-epoxy functionality (± 2.8).
  • These additional reactive sites, as compared to a bisphenol-A type epoxy resin, produce tightly cross-linked cured systems.
  • This makes epoxy novolac resins especially useful in adhesives, electrical and structural laminates, coatings and castings for elevated temperature service.
  • D.E.N. 431 Epoxy Novolac Resin will exhibit chemical resistance and elevated temperature performance between the properties of D.E.N.® 438ᵀᴹ Epoxy Novolac Resin and the bisphenol A based liquid epoxy resins.
  • Adhesives based on D.E.N.® 431 Epoxy Novolac Resins are ideal for use as binders for abrasives in grinding and polishing products.
  • The low viscosity of D.E.N.® 431 Epoxy Novolac Resin makes it especially suited for electrical varnishes, filament-wound pipes and highly chemical resistant coatings for storage tanks.
