Introduction
MELCROSS-26
Crosslinking agent has fast
curing properties, mar
resistance properties and provides
films with good hardness and
resistance properties, high
gloss benefits. This
resin shows a medium reactivity
and a medium tendency for self
condensation in a range of polymer
backbone resins, providing films
with very good gloss, hardness,
adhesion, and chemical resistance
properties. MELCROSS-26
amino resin does not need the
addition of an acid catalyst
to the formulation to
get effective cure at
general stoving conditions.
The acidity of alkyd,
polyester or acrylic is sufficient
to initiate the curing process.
If you use weak organic
or inorganic acids as additionally
catalyst to the formulation,
you can get very effective results.
Acid
catalyzed coatings may be cured
as low as 110-150∑C
for 15-20 minutes. To
control the stability, you can
use tertiary amins for neutralization
and PH adjustment. MELCROSS-26
has good compatibility with
a range of backbone polymers
and has been designed for a
wide range of medium solids,
high glossy general industrial
stoving applications.
