In the paint and coatings industry, wollastonite powder serves as a filler for paints and coatings, improving the physical and chemical properties of products, enhancing durability and weather resistance, reducing paint gloss, increasing coating expansion capacity, minimizing cracks, and also lowering oil absorption while boosting corrosion resistance. Wollastonite has a bright luster and high reflectivity, making it suitable for producing high-quality white paints and clear, transparent colored paints. Acicular wollastonite powder exhibits excellent matting properties, high color coverage with uniform distribution, and UV resistance. It is widely used in interior wall coatings, exterior wall coatings, specialty coatings, and latex paints. The finer the particle size and the higher the whiteness and pH value, the better the paint's color and application performance. Additionally, due to its alkaline nature, paint containing wollastonite can be used as an anti-corrosion coating for metal equipment such as steel.
