Lithopone 30% L

LITHOPONE 30% DS is an organically coated white pigment based on co-precipitated zinc sulfide (ZnS) and barium sulfate (BaSO₄). It is free from inorganic surface treatment, helping reduce volatiles and lacing in plastic applications. The product is chemically resistant within the pH range of 4 to 12 and offers excellent dispersibility.

The pigment has a refractive index of 1.86, high brightness, and a neutral hue. Its low absorption in the near UV range enhances compatibility with optical brighteners compared to other inorganic white pigments.

• Low abrasiveness (Mohs hardness of ca. 3) reduces screw and knife wear, making it suitable for abrasion-sensitive applications.
• Bimodal particle size contributes to high extruder yield, increased impact strength, reduced friction, and enhanced melt flow in plastics.
• Can partially replace titanium dioxide in plastics and powder coatings.
• Low binder demand enables viscosity adjustments in coatings.

As with all fine powders, handling zinc sulfide pigments can generate airborne dust. Good industrial hygiene practices should be observed to avoid dust generation and inhalation. For more information, refer to the material safety data sheet.

The product should be stored unstacked in dry and closed rooms at normal temperature and humidity. To achieve the best results, use within 12 months from the delivery date.
