D.E.H.* 82 epoxy curing agent is a
phenolic hardner and a reaction product
of liquid epoxy resin and bisphenol-
A containing a curing accelerator
and a polyacrylate flow modifier.
D.E.H. 82 curing agent is designed for
powder coating applications. It is fully
compatible with epoxy resins and it
can be formulated into low bake
(130°C) decorative or protective powder
coatings. The relatively high reactivity
of D.E.H. 82 curing agent can be
reduced by substituting part of the
hardener with D.E.H. 80 curing agent.
The accelerator present in D.E.H. 82
curing agent tends to promote a catalytic
crosslinking of the epoxy resin
baking and for this reason it is suggested
that a 10 to 20 % molar excess
of epoxy over the hardener be
used when formulating with D.E.H. 82
curing agent in order to produce cured
coatings with optimum properties. As a
result of the relatively high accelerator
concentration present in D.E.H. 82
hardener, the powder coating formulations
based solely on this hardener
may have a limited storage stability and
particular care should be taken during
the summer months or in hot climates
to prevent a rapid deterioration of the
formulated powder coatings.
Phenolic hardner and a reaction product of liquid epoxy resin and bisphenol- A containing a curing accelerator and a polyacrylate flow modifier. Used for powder coating applications. Offers compatibility with epoxy resins. Suits for low bake decorative and protective powder coatings.
