Ultra-Fine High-Whiteness Wollastonite for Architectural Coatings & Industrial Paints

Ultra-fine high-whiteness wollastonite is a premium calcium silicate mineral filler engineered for architectural coatings and industrial paints. Processed via advanced precision beneficiation, ultra-fine grinding, and purification technology, it boasts exceptional whiteness (≥93%), a ultra-fine particle size distribution (1250–5000 mesh, customizable), and a low oil absorption rate (18–25 g/100g), making it a high-performance additive for diverse coating formulations.

Designed to elevate paint performance, it enhances opacity, coverage, and color retention while improving the scratch resistance and weatherability of coating films. Its acicular crystal structure ensures strong adhesion to resin matrices (acrylic, epoxy, alkyd, polyurethane), reducing sagging during application and boosting the durability of painted surfaces—ideal for exterior walls, industrial equipment, metal structures, and architectural facades. The ultra-fine particles contribute to a smooth, high-gloss finish, minimizing surface roughness and enhancing the aesthetic appeal of coatings.

Eco-friendly, non-toxic, and compliant with ISO 9001/ROHS standards, it is compatible with both water-based and solvent-based coatings, reducing pigment consumption and material costs without compromising quality. Resistant to acid and alkali corrosion, it maintains stable performance in harsh environments, extending the service life of painted substrates. Perfect for coating manufacturers seeking to develop high-quality, cost-effective, and durable architectural and industrial paint solutions.
