JH25 can be used as a Cross linking agent for medium solid or water
borne finishes, Automotive or general metals finishes, Coil or
This resin is a 78-82% solids in iso-butanol, High viscous liquid.
JH25 resin is a high degree methylated melamine formaldehyde
crosslinking agent with a high imino functionality.
And a low methylol content and high imino functionality resin is a
very effective crosslinking agent for epoxy, alkyd, polyester or
acrylic resins. Delivers medium solids coatings.
degree of polymerization
With waterborne alkyd resin, water soluble acrylic resin mixture
water-based paint;Can also with solvent-based acrylic resin, alkyd
resin, polyester resin, such as preparation of the lacquer that
bake, no additional catalyst can fast curing, after crosslinking
curing, the balance of the coating have excellent hardness and
flexibility.Widely used in general industrial paint, fast curing
coil coatings, automotive original paint, metal paint, oil electric
plating.Because it partly soluble in water, but also widely used in
water-borne acrylic amino paint (dip coating), water-based metal
paint (dip coating or electrostatic spraying), water-based glass
paint (coating) and part of printing, reaction type structure
adhesive coatings, without the need for stringent measurement, room
temperature curing, the bonding degree is high, easy to use, etc.
JH25 amino resin is a very effective crosslinker for backbone
polymers containing hydroxyl, amide and carboxyl functional groups,
such as epoxy, alkyd/polyester or acrylic resins. Partially soluble
in water and has an excellent compatibility with water soluble
polymers. Suitable for coil coating and industrial paint of baking
enamels, providing less weight loss during the baking process. Fast
cure response, Higher resistance properties, No strong acid
JH 25 resin is suitable for a wide range of industrial stoving
systems, providing less weight loss during the backing process in
comparison with the partially methylated melamine crosslinking
agents. This makes JH25 resin suitable for medium solids coating
This resin also provides fast cure response, higher resistance
properties, and no strong acid catalyst required in the normal
baking enamel systems.
Formulated systems containing JH25 resin have to be stabilized with
primary alcohols, amins or with a combination of these materials.
Acid catalyzed coatings may be cured as low as 110-150°C for 20-30
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.
