MELCROSS
83 is
a
minimum 98% solids
methylated, ethylated
benzoguanamine-formaldehyde
crosslinking agent
with a high degree
of alkylation,
a low methylol

This
resin is a very effective crosslinking
agent for backbone polymers
containing hydroxyl,
carboxyl
or amide functional groups
such as epoxy, alkyd/polyester
or acrylic resins.
MELCROSS-83
resin is insoluble in water.
Due to its hydrophobic
nature, this resin has to be
dissolved initially in the organic
phase of the water reducible
backbone polymers.

Introduction
MELCROSS-83 resin is
suitable for a wide range of
general industrial stoving finishes,
providing high detergent and
chemical resistance properties.
This resin is a very effective
crosslinking agent for backbone
polymers containing hydroxyl,
carboxyl
or amide functional groups
such as epoxy, alkyd/polyester
or acrylic resins Designed
for Can coating with polyester
and epoxy resin. 98%
high solids type resin have
Excellent detergent resistance
and chemical resistance, salt
spray resistance. Methylated/Ethylated
type Benzoguanamine resin gives
very good hardness and nontoxic
films for foods and drinks.
MELCROSS-83
resin dissolves very well in
the solvents of alcohols, ketones,
esters and aromatic hydrocarbons
but partially in aliphatic hydrocarbons
and not solves in water.
The
compatibility with alkyd resins,
polyester resins, acrylic resins
and epoxy resins is very good.
Storage
stabily at room temperatures
is minimum one year after delivery.
Avoid
direct sunshine and store at
minimum 5∑C.
At lower temperatures
crystallization may occur.
Acid
catalyzed coatings may be cured
as low as 140-160∑C
for 20 minutes.
To control the stability,
you can use primary alcohols,
amins or with combination
of these for neutralization
and PH adjustment.
SAFETY
General
Attention must be paid
to the normal precautions for
handling chemicals and to the
measures prescript in the local
health regulations.
The work place must be
well ventilated, skin care measures
should be adapted and safety
google should be worn.
