Barium Sulfate Precipitated has the best spacing capability to TiO2 powder. It has the most ideal surface energy, and the most stable combination with other organic and inorganic dye particles. It can be highly spread and supported TiO2 particles and other dye particles to improve viscosity and dispersion stability of the painting material, and prevent the invasion of big particles, so totally ensure the entire function of products.

Application of barium sulfate precipitated:
1. Paint and coatings
Automotive paint systems: For use in extender systems, due to gloss retention and excellent mechanical properties.
High Solids Paints: Partial substitution of Barium sulfate precipitated for other pigments achieves significant reduction of volatile matters (VOC).
Pigment pastes: Greater color intensity and brilliance due to improved dispersion of colored pigment (using 10% Barium sulfate precipitated, for example).
Increase resistance to weathering in laminates for outdoor use.
Enhances the efficiency of extenders and fillers in white and colored pigmented decorative papers by expelling air in the pores.
More uniform resin penetration and reduction of mottling in colored decorative papers.
Paper sizes: High whiteness, gloss and good printability (in cardboard and paperboard sizes, for example)
3. Plastics and rubber
Thermoplastics: Enhances the efficiency of colored pigments in master batches and pastes. Imparts a feeling of quality and luxury. Has a positive effect on mechanical and visual properties, in particular impact strength and gloss, in thermoplastic compounds.
Elastomers: Particularly suitable as an extender, since free of rubber toxins.
No effects on storage stability and resistance to aging.
Thermosets: For formulation of color adjustments.
Combination with colored pigment permits attainment of brilliant and reproducible hues and perfect surfaces.
