Calcined Kaolin is a processed form of kaolin clay achieved through controlled heating, which removes chemically bound water and enhances its physical and chemical properties. The result is a fine, white to off-white powder primarily composed of aluminum silicate. This form of kaolin exhibits improved brightness, increased hardness, and reduced oil absorption, making it suitable for applications requiring high durability and color stability. Finstar supplies Calcined Kaolin typically with a particle size optimized around 2-5 microns, ensuring consistent dispersibility in formulations. It is supplied as a dry powder under typical packaging options of 25 kg bags and bulk bags, with special packaging available on request. Buyers should handle the material in dry conditions, protect it from moisture, and store it in temperatures below 40°C to maintain its quality and prevent agglomeration.
In coatings and paints, Calcined Kaolin acts as an extender and filler that enhances opacity and durability while reducing production costs by replacing more expensive pigment components. Its hardness and chemical inertness improve abrasion resistance and weatherability of finished coatings. Moreover, in paper applications, calcined kaolin improves brightness and printability without compromising the strength of the paper. This enables manufacturers to produce improved quality products with consistent performance under varying environmental conditions.
