D.E.H.* 81 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. 81 epoxy curing agent is a
phenolic hardener designed for powder
coating applications. It is fully
compatible with epoxy resins and it
can be formulated into decorative or
protective powder coatings. When formulated
into white or pastel shades,
formulations based on D.E.H. 81 curing
agent may exhibit a tendency
toward yellowing when subjected to
high baking temperatures or to overbake.
The medium reactivity of D.E.H.
81 curing agent can be increased or
reduced by substituting part of the
hardener with D.E.H. 82 or D.E.H. 80
curing agents respectively. The accelerator
present in D.E.H. 81 curing
agent tends to promote a catalytic
crosslinking of the epoxy resin during
baking and for this reason it is suggested
that a 5 to 10% molar excess
of epoxy over the hardener be used
when formulating with D.E.H. 81 curing
agent to produce cured coatings
with optimum properties.
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 decorative and protective powder coatings.
