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
