D.E.R.™ 323

D.E.R.™ 323 Liquid Epoxy Resin is a low viscosity, C12-C14 aliphatic glycidyl ether diluted standard bisphenol A based liquid epoxy resin. Its surface tension is lower than other reactive diluent diluted epoxy resins and results in better surface wetting, better adhesion, and will have slightly lower viscosity at any given filler loading.

Used in:

  • Adhesives
  • Casting and Tooling
  • Civil Engineering
  • Composites
  • Marine and Protective Coatings
  • Potting and Encapsulation


  • Offers lower surface tension
  • Superior surface wetting and adhesion
  • Slightly lower viscosity at any given filler loading
  • Offers better filler acceptance, reduced odor, lower vaporpressure, and less potential for handling hazards
  • Increased pot-life and flexibility (impact resistance)
  • Improved acid resistance
  • Works effectively with a wide variety of curing agents at ambienttemperatures
