(Wood coatings, anti-corrosion coatings, plastic coatings, automotive coatings, industrial coatings) solvent-based baking paint, PU coating, epoxy coating, coiled material coating, acrylic system

Characteristics and use

Fluorine-modified polymer leveling agent can quickly reduce the surface tension of the coating system. It has good leveling and recoating properties

Improve the wetting of the substrate and prevent the shrinkage, pinhole, fisheye and other defects of the coating film, and obtain good flatness

It is stable, not easy to hydrolyze, has good light resistance and aging resistance, and does not volatilize. Therefore, in addition to improving the leveling property, the paint system also has the effect of plasticizing

Good compatibility with most paint systems

Addition amount and use method

The addition amount depends on the coating system, which is generally 0.05-0.50% for the total amount

Please test the most appropriate dosage and compatibility with the coating system before use

Storage

Store in a cool and ventilated place, keep the container tightly, keep away from heat and fire sources, and store at 0 to 40 ℃
