D.E.H.* 90 epoxy curing agent is a
solid reaction product of liquid epoxy
resin and polyphenols, containing a
curing accelerator and 2 wt.% of a
polyacrylate flow modifier.
D.E.H. 90 phenolic hardener has
been designed for powder coating
applications which require the fast
cure capabilities of phenolic hardeners
combined with superior adhesion
properties to metal substrates. It can
be formulated into both decorative
powder coatings or protective coatings.
D.E.H. 90 epoxy phenolic hardener
can be used alone or in combination
with other D.E.H. 80 series
phenolic hardeners, with which it is
fully compatible, to enhance the adhesion
properties to metal substrates.
The accelerator present in D.E.H. 90
phenolic hardener tends to have a
catalytic effect on the crosslinking of
epoxy resins. For this reason, a 10 to
20 % molar excess of epoxy over the
hardener is recommended when formulating
with D.E.H. 90 phenolic
hardener to produce cured coatings
with excellent mechanical properties.
When formulated into white or pastel
shades, D.E.H. 90 phenolic hardener
may exhibit a tendency towards yellowing
when subjected to high temperatures
or to over-bake.
