Lithopone B311 for Paint

Product Description

B301: white pigment ,zinc sulfide content is 28%. Covering power is stronger than zinc oxide, worse than titanium dioxide, and good heat resistance.

B302:white pigment ,zinc sulfide content is 28%. After surface treatment, it has better dispersion than B301

B311:white pigment ,zinc sulfide content is 30%. Compared with B301, it has stronger covering power and fading power also better dispersibility

Usage:
Used for coloring paint, ink, rubber, rubber products, paper, lacquer cloth, oil cloth, leather, watercolor pigment, paper, enamel etc . It also used as adhesive in the production of electric beads

Inorganic white pigment, widely used in polyolefin, vinyl resin, ABS resin, polystyrene, polycarbonate, nylon, polyformaldehyde and other plastics, as the white pigment of paint&ink. It is bad use for polyurethane and amino resin, and cannot use for fluoroplastics.
