Product Information

D.E.R.™ 351
Liquid Epoxy Resin

Description D.E.R.™ 351 Liquid Epoxy Resin is a reaction product of epichlorohydrin with bisphenol A
and bisphenol F.

Introduction D.E.R. 351 Liquid Epoxy Resin is a (reactive) diluent free epoxy resin of lower viscosity
than D.E.R. 352 Epoxy Resin. D.E.R. 351 Liquid Epoxy Resin combines the performance
properties of standard bisphenol A liquid epoxy resin with the low viscosity of bisphenol F
liquid epoxy resin.

Crystallization, often a problem with conventional bisphenol A or bisphenol F based liquid

epoxy resins, is essentially non-existent with D.E.R. 351 Liquid Epoxy Resin. D.E.R. 351
Epoxy Resin is compatible with common liquid epoxy resins and can also be blended with
other materials (diluents, hydrocarbon resins etc.) to increase flexibility or obtain other
specific properties.

Typical This product is suitable for use in applications such as:

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