D.E.R.* 332 epoxy resin is a high
purity bisphenol-A diglycidyl ether.
The uniqueness of D.E.R. 332 liquid
epoxy resin is reflected in its maximum
epoxy equivalent weight of 176
grams/equivalent (the chemically pure
diglycidyl ether of bisphenol-A has an
epoxy equivalent weight of 170 g/eq).
Because of its high purity and low
polymer fractions content, D.E.R. 332
epoxy resin assures uniform performance
and exceptionally low viscosity,
low chloride content and light color.
Under some cure conditions this
epoxy resin provides improved elevated
temperature properties over standard
bisphenol-A based epoxy resins
such as D.E.R. 331 epoxy resin for
example. D.E.R. 332 epoxy resin is
used mainly in filament winding, electrical
laminates and encapsulation
applications. A wide variety of curing
agents is available to cure this liquid
epoxy resin at ambient conditions.
Most frequently used are cycloaliphatic
polyamines, polyamides,
amidoamines, and modified versions
of these. These systems are sometimes
cured at elevated temperatures
to improve selected properties such
as chemical resistance and glass
transition temperature. Elevated temperature
cures are necessary and
long post-cures are required to develop
full end properties if anhydride or
catalytic curing agents are employed.
NOTE: D.E.R. 332 epoxy resin might
crystallize. This reversible, physical
phenomena can be greatly avoided by
storing the resin at temperatures not
below 25ºC.
marine and protective coatings
photocure industrial coatings
High purity bisphenol-A diglycidyl ether. Used in marine, protective and photocure industrial coatings. Offers uniform performance and very low viscosity, low chloride content and light color. Provides improved elevated temperature properties. Can be cured by cycloaliphatic
polyamines, polyamides, amidoamines, and modified versions of these. Gives improved chemical resistance and glass transition temperature when cured at elevated temperatures.
