Calcined kaolin

Calcined kaolin (CAS 92704-41-1), also marketed under trade names such as Satintone 1 and M 100, is a thermally processed aluminum silicate clay used as a functional filler and rheology modifier across industrial manufacturing.

Where is Calcined kaolin used?

• Coatings and paints: improves opacity, controls sheen, reduces titanium dioxide demand
• Paper and board: coating pigment and filler enhancing printability, brightness, surface smoothness in offset and flexographic printing substrates
• Plastics and rubber: improves dimensional stability, stiffness, electrical resistance in cable insulation and molded components
• Adhesives and sealants: adjusts viscosity and extends formulations without compromising bond performance
• Calcination drives off hydroxyl groups, producing a harder, more chemically inert material than standard hydrous kaolin.

Commercial specifications

• Dry white powder in a range of particle size distributions
• Specific surface area and brightness specifications vary by application
• Bulk bags and multi-wall paper sacks
