D.E.R.* 337 epoxy resin is a liquid
to semi-solid reaction product of
epichlorohydrin and bisphenol-A.
D.E.R. 337 epoxy resin is an intermediate
epoxy equivalent weight epoxy
resin, mainly used in adhesives and
protective coatings, or as a modifier
for other epoxy resins to improve
impact strength, extensibility and
adhesion. The excellent resistance
and physical properties have established
D.E.R. 337 epoxy resin as a
major raw material for epoxy coal tar
combinations and higher solids content
marine coatings. D.E.R. 337 can
be used to modify performance as
well as handling properties of liquid
epoxy resin, such as D.E.R. 331, and
epoxy novolac type of resins, such as
D.E.N.* 431 and D.E.N. 438 epoxy
novolac 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 required to
develop full end properties if anhydride
or catalytic curing agents are
employed.
Marine & Protective Coatings
Liquid to semi-solid, intermediate epoxy equivalent weight, reaction product of epichlorohydrin and bisphenol-A. Used in protective coatings, higher solids content marine coatings or as a modifier for other epoxy resins to improve impact strength, extensibility and adhesion. Provides very good resistance and physical properties. Can be used to modify performance and handling properties of liquid epoxy resin. Can be cured by aliphatic polyamines, polyamides and modified versions of these.
