JH25 can be used as a Cross linking agent for medium solid or water borne finishes, Automotive or general metals finishes, Coil or container coatings.
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.

Application
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.

Introduction
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 catalyst required.
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 formulations.
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 minutes.

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.
