D.E.R. 354 Liquid Epoxy Resin

D.E.R 354
Liquid Epoxy Resin
Description
D.E.R.* 354 liquid epoxy resin is a standard liquid epoxy resin based on the reaction product
of bisphenol-F and epichlorohydrin.
Introduction
D.E.R. 354 liquid epoxy resin is an unmodified bisphenol-F based liquid, low viscosity epoxy
resin. It is compatible with common epoxy resins and can be blended with them in any ratio.
It achieves a high degree of cure at ambient temperatures, providing improved resistance
performance against solvents compared to standard bisphenol-A liquid epoxy resins. A wide
variety of curing agents is available to cure this resin at ambient conditions. Most frequently
used are aliphatic polyamines, polyamides and modified versions of these. Elevated
temperature cure is necessary and post-cure is required to develop full end properties if
anhydride or catalytic curing agents are employed. D.E.R. 354 epoxy resin may be used
alone but is more frequently used in combination with standard bisphenol-A liquid epoxy
resins such as D.E.R. 330 or D.E.R. 331 epoxy resin. By using suitable combinations of
bisphenol-A and bisphenol-F epoxy resins, not only is the viscosity reduced but the tendency
to crystallise is almost eliminated.
Note: D.E.R. 354 liquid epoxy resin might crystallize. This reversible physical phenomena
can be greatly avoided by storage at temperatures not below 25 C.
