Product Description:


Lithopone 30% DS

 

The product:

LITHOPONE 30% DS is an organically coated white pigment based on a co-precipitated zinc sulfide / barium sulfate.

 

Typical Properties:

 Low binder requirement

 Excellent dispersibility

 Neutral hue

 Low abrasiveness, thanks to low Mohs hardness

 

Applications:

 Paints and coatings

Suitable for use in matt and semimatt powder-coating systems, thanks to its favorable rheological properties and excellent compatibility with coloured pigments.

 Paper

Achieves high dry opacity in the pulp. Its good retention permits use in pigment size preparations. Bimodal particle distribution improves the porosity of the paper.

 Plastics and rubber

TiO2 can be partially replaced with LITHOPONE 30% DS in thermoplastic masterbatches.This products low binder requirement compared to TiO2 permits higher pigment concentrations.

The use of LITHOPONE 30% DS makes it possible to reduce friction and abrasion in production of master batches and films. The extremely low absorption which LITHOPONE 30% DS possesses in the near UV range significantly improves the effects of optical brighteners and polymerization initiators. LITHOPONE 30% DS produces good rheology in duroplastic moulding compounds without causing abrasion.

Lithopone is a white pigment composed of a mixture of barium sulfate (68 - 70 %) and zinc sulfide (28 - 30%) with trace amounts of zinc oxide. It is produced by precipitation through filtering, heating and quenching works. Lithopone has mostly been replaced by titanium dioxide which is more durable, but it is much cheaper. It is used as a base for lake pigment and used as a inert pigment for paint, ink and cosmetics as well as in a large range of applications in plastic industry. It is used as a filler in paper, leather, and linoleum.
