Additional Information
  • D.E.R.® 331 Epoxy Resin is the most widely used general purpose liquid epoxy resin.
  • It is recognized as the standard from which many variations have been developed.
  • A wide variety of curing agents is available to cure liquid epoxy resins at ambient conditions.
  • The most frequently used are aliphatic polyamines, polyamides, amidoamines, cycloaliphatic amines and modified versions of these curing agents.
  • Curing may also be done at an elevated temperature to improve selected properties such as chemical resistance and glass transition temperature.
  • If anhydride or catalytic curing agents are employed, elevated temperature cures are necessary and long post-cures are required to develop full end properties.
