Aluminium Silicate

About the Product

Aluminium Silicate having the general formula Al2SiO3, is remarkable for its use as filler and antisettling agent in paint and as semi-reinforcing agent in rubber. It can be manufactured either by precipitation or by processing of the naturally occurring aluminium silicate minerals. The precipitated variety gives better properties due to smaller particle sizes and a higher white strength value.

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. As an Aluminium Silicate manufacturer in India our R&D department has developed the precipitation process to provide accurate control of particle size and surface area. The properties of Aluminium silicate powder have been optimized in our different grades according to the application.

Advantages of Our Products in Paints

• Part of white pigment like titanium dioxide (10% or more) can be replaced without loss of opacity.
• Give faster surface and through-drying in product which also stand up better to abrasive treatment.
• Excellent substrates for high gloss finishes as they ensure good levelling out.
• Give excellent thixotropy and facilitate dripless application.
• Act as anti-setting agents for pigments and fillers. The viscosity of decorative paints containing our product is highly constant over extended periods of time. Being basic, they also have positive effect on storage stability. As Aluminium Silicate exporters in India, we supply grades trusted by paint manufacturers worldwide.

Advantages in Rubber

The particles of the filler used interact with the polymer, thus changing the properties of the mix and vulcanized material. For a filler with definite chemical composition, this interaction becomes more intensive as the surface area of the filler particles increases. Due to fine micronization of our products, they have very large surface area and thus give excellent properties in terms of tensile strength, modulus and resistance to tear and abrasion. 

They are particularly suitable for soling and microcellular sheets as they give relatively fast cures and enable production of soling materials to be streamlined. Being among the leading Aluminium Silicate manufacturers in the world, our products are widely used in international rubber applications.
