Characteristics and use

It is a fluorine-modified polymer leveling agent with 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 leveling

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, generally 0.1-0.5% 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 ℃
