Contact SupplierWe are one of the major Exporters of Aluminium Silicate in the market. Aluminium Silicate which is chemically denoted as Al2 Si O3 is commonly used as filler as well as anti settling agent in paint. It is also used as semi reinforcing agent in rubber. Aluminium Silicate is available in two of its major forms i.e. Sodium Aluminium Silicate and Potassium Aluminium Silicate. " We also manufacture sodium aluminium silicate UNISIL NK-20 AHS which is used as titanium dioxide replacement in matt emulsion paints".

MANUFACTURING PROCESS
Aluminium Silicate is first precipitated in large tanks. It is then filtered and washed dried and micronized on most modern plant to prevent contamination. Our R&D department has developed the precipitation process to provide accurate control of particle size and surface area. The properties have been optimized in our different grades according to the application.
