D.E.R.* 353 liquid epoxy resin is a
C12 - C14 aliphatic chain glycidyl ether
modified bisphenol-A/F based resin.
The performance of D.E.R. 353 liquid
epoxy resin in ambient curing coating/
flooring formulations is similar to
those obtained with D.E.R. 324
epoxy resin. However, the tendency
to crystallize is much lower for
D.E.R. 353 epoxy resin than for
D.E.R. 324. This enhanced crystallization
resistance caused by the
bisphenol-A/F epoxy resin blend
greatly improves the formulation stability,
reduces the handling costs,
makes emptying drums easier. The
diluent lowers the surface tension
which results in excellent surface
wetting and adhesion. The reactive
diluent increases pot-life as well as
flexibility (impact resistance), limits
the solvent resistance somewhat but
improves the acid resistance. A wide
variety of curing agents is available
to cure this liquid epoxy resin at
ambient conditions. Most frequently
used are (cyclo) aliphatic
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.
marine and protective coatings
Aliphatic glycidyl ether modified bisphenol-A/F based resin. Used in ambient curing marine and protective coatings. Possesses enhanced crystallization resistance, improved stability and reduced handling costs. Offers very good surface wetting and adhesion. Provides increased acid resistance, pot-life, flexibility and limited solvent resistance. Can be cured by (cyclo) aliphatic polyamines, polyamides, amidoamines, and modified versions of these. Can be cured at elevated temperatures to improve chemical resistance and glass transition temperature.
