The raw material for Micro-Mineral Catca product is the mineral Musco-vite a hydrous silicate of potassium and Aluminium. Catca is characterized by its perfect cleavage and even when micronised. The platy particle shape is maintained.
Catca with its typical lamellar particle structure is primarily useful wherever a high rate of resistance against chemicals, heat and ultra violet light is required. Hence is ideal for external paint and anti-corrosion paints such as marine paint. It promotes a matt finish and acts as an anti-cracking agent as well as helps to control paint flow and enhances scrub resistance. |
