    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
