In the competitive world of coatings and paints, achieving specific performance characteristics and aesthetic qualities is crucial for market success. Manufacturers constantly seek high-quality raw materials that can offer improved properties and cost-effectiveness. Calcined kaolin powder, particularly grades with high whiteness, has emerged as a valuable additive in various coating formulations. As a premier supplier of industrial chemicals, NINGBO INNO PHARMCHEM CO.,LTD. offers premium calcined kaolin powder that can significantly elevate the performance of your coating products. If you are looking to buy calcined kaolin powder for your coating needs, consider us your reliable partner.

The Role of Calcined Kaolin in Coatings

Calcined kaolin serves multiple functions in coating formulations. Its primary benefits stem from its fine particle size, high purity, and the process of calcination. The calcination process, which drives off chemically bound water, results in a more chemically inert and thermally stable material. This translates to improved durability and resistance to degradation in the final coating. Furthermore, the high whiteness of calcined kaolin (typically 94-95%) acts as an excellent extender pigment, contributing to the opacity and brightness of paints and coatings without compromising color neutrality. Manufacturers often seek this specific grade when developing white or light-colored formulations.

Performance Enhancements and Applications

Incorporating calcined kaolin powder into coatings can lead to several performance enhancements:

  • Improved Rheology: The particle shape and surface characteristics of calcined kaolin can help control the viscosity and flow properties of the coating, making application smoother and more efficient.
  • Enhanced Opacity and Hiding Power: Its high refractive index and whiteness contribute to better coverage, allowing for thinner coats or reduced pigment loading in some formulations.
  • Increased Scrub and Abrasion Resistance: The hardness and inertness of calcined kaolin can improve the coating's resistance to mechanical wear and tear, extending its lifespan, particularly in high-traffic areas.
  • Better Weatherability: Its chemical stability helps protect the coating from UV degradation and environmental factors, making it suitable for exterior applications.
  • Reduced VOCs: As an inorganic filler, it can help reduce the overall binder and solvent content, potentially contributing to lower Volatile Organic Compound (VOC) levels.
