Lithopone B301

Inorganic white pigment - Factory supply & bulk wholesale

Lithopone B301 also known as zinc barium white, is a non-toxic white powder that is insoluble in water. It decomposes with acids to release hydrogen sulfide and does not react with hydrogen sulfide or salt.

It has good heat resistance, can improve weather resistance, prevent algae, reduce costs and has excellent shading power and whiteness.

Key features

  • High hiding power and excellent tinting strength
  • Good dispersibility in organic and aqueous systems
  • Excellent opacity and whiteness for coatings and plastics
  • Factory direct — bulk packaging, reliable supply chain

Performance & Advantages

  • Consistent particle size distribution for uniform gloss and color strength
  • Low tendency to yellowing in many polymer matrices
  • Easy to mill and disperse in common grinding equipment

Application:

It is mainly applied in various high-end indoor and outdoor coatings, interior and exterior wall latex paints, industrial coatings, powder coatings, as well as in fields such as plastics, rubber, ink, leather, and paper production.

Package:

The product is packaged in a composite bag with inner plastic and outer woven material.

The net weight is 25 kilograms per bag.
