Calcined Kaolin Powder

Calcinated Kaolin for Paints, Coating & Pigments are heat processed into high-quality calcined pigments. These are used as pigment extender for Paints, polymers and plastics. The manufacturing process is designed for close control of the formation of the finished porous aggregate structure, leading to increased performance at reduced cost and improving the performance of paints, plastic, paper and rubber. It is a high brightness clay, with exceptional light scattering properties which give rise to the product’s excellent opacifying properties, making it an ideal TiO2 extender (can replace 20% TiO2) in many industrial applications.

Chemical Composition

Calcined Kaolin Powder primarily consists of Kaolinite, a mineral composed of aluminum silicate. The exact chemical composition may vary depending on the source and production process, but it typically contains high levels of aluminum oxide (Al2O3) and silica dioxide (SiO2). Trace amounts of other minerals may be present, depending on the specific characteristics of the Kaolin clay used.

In summary, Calcined Kaolin Powder is a versatile mineral powder with exceptional brightness, whiteness, and a range of desirable properties. Its applications span industries such as ceramics, paints, coatings, plastics, rubber, and more. With its superior performance, Calcined Kaolin Powder enhances product quality, performance, and efficiency while offering environmental sustainability. Choose Calcined Kaolin Powder for your industry needs and experience its transformative impact on your applications.
