D.E.H.* 80 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. 80 epoxy curing agent is
designed for powder coating applications.
It is fully compatible with epoxy
resins and it can be formulated into
high gloss and good flow decorative
powder coatings or into protective
coatings. When formulated into white
or pastel shades, formulations based
on D.E.H. 80 curing agent may exhibit
a tendency towards yellowing when
subjected to high baking temperatures
or to over-bake. The moderate reactivity
of D.E.H. 80 curing agent can be
increased by using either D.E.H. 81 or
D.E.H. 82 hardeners as part of the formulation.
The performance of phenolic
cured epoxy powder coating formulations
and particularly their adhesion
to metal substrates will be greatly
affected by the quality of the surface
preparation, and suitable pretreatments
such as phosphates or
blast cleaning are suggested as a
minimum requirement.
This product is suitable for use in powder coating applications.
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 high gloss and good flow decorative powder coatings and protective coatings.
