Paints and Coatings: In coatings, fine acicular particles act as a good flattening
agent and allow paint to settle out after application to produce a
dry film of uniform thickness, and the interlocking particles
improve toughness and durability of the coating with excellent tint
retention, scrub, and weather resistance. High brightness and
whiteness reduce pigment load and typically very low oil
absorption, reduces the volume of binder required and contributes
to reduced pigment costs. As noted earlier, wollastonite can also
act as a pH buffer for improved in-can paint stability over long
periods of time. The acicular structure and alkaline nature of
wollastonite also make it an ideal auxiliary pigment in industrial
coatings and primers for improved corrosion resistance. Wollastonite is an inorganic needle-like mineral, and wollastonite products have very noticeable acicular and long fiber structures .It is characterized by non-toxicity, chemical corrosion resistance, good thermal stability and dimensional stability, glass and pearl luster, low water absorption and oil absorption value, excellent mechanical and electrical properties,even reinforcing effect. Wollastonite products with long fibers and easy separation, low iron content and high whiteness. Wollatonite is Widely used in plastics, rubber, asbestos substitutes, paint coatings and other fields, it can increase the hardness, flexural strength, impact resistance of products, improve the electrical properties of materials, improve thermal stability and dimensional stability, and is the most promising application field. It is also used in the ceramics and metallurgical industries. The SiO2 and CaO components in wollastonite provide low expansion rate and good thermal shock resistance.
Wollastonite is used for many different industrial purposes, including the production of: Engineering technical plastics Fluoro elastomer e.g. for oil sealing heat-resistant refractory ceramics metallurgy wood composites adhesives filler in paint, paper and other products friction products such as brake pads a. good compatibility. b. Excellent Stability and products meets clients requirement absolutely c. Excellent performance on physical properties
