产品系列:Waterborne epoxy ester resin

CM-3370 waterborne epoxy modified acrylic resin

 

characteristic

Fast offline packaging and good adhesion on metal surfaces

purpose

Preparation of anti-corrosion water-based self drying and low-temperature baking series mixed paint, enamel paint, and motor casing

Low temperature drying or high temperature amino baking paint.

Product Performance

Appearance: brownish yellow viscous liquid

Solid content% (150 ℃, 1h): 67 ± 2

Viscosity, rotational viscometer, cps:40000-100000

 

Type: Water based epoxy ester

 

 

Application reference

The resin has been neutralized, and when making clear varnish, use dimethyl ethanolamine to adjust the pH value to 9 or above;

Self drying, oxidation crosslinking type, requires the use of a drying agent, with an addition amount of about 3% of the resin content;

Water dispersible resin, which can participate in slurry grinding;

The resin based paint process is similar to solvent based paint, but attention should be paid to changes in pH value and the impact of pigments on the resin
