Additional Information
  • D.E.R.® 321 Liquid Epoxy Resin is ortho-cresyl glycidyl ether diluted standard bisphenol A based liquid epoxy resin, of extremely low viscosity.
  • The low viscosity is advantageous in compounds containing large amounts of filler. D.E.R.® 321 Resin has a cure rate similar to unmodified bisphenol A based liquid epoxy resins.
  • The reactive diluent contained in D.E.R.® 321 Epoxy Resin limits somewhat the solvent resistance, however, an improved acid resistance can be observed using D.E.R.® 321 Epoxy Resin in stead of D.E.R.® 321 Liquid Epoxy Resin.
  • D.E.R.® 321 Liquid Epoxy Resin exhibits a very low tendency to crystallize.
  • D.E.R.® 321 Epoxy Resin can be hot or cold cured by blending with polyamine, polyamide and modified versions of these.
  • Elevated temperature cures are necessary and post-cures required to develop full end properties if anhydride or catalytic curing agents are employed.
