The silicates are the largest and most complex class of minerals by far.

Approximately 30% of all minerals are silicates, and many geologists estimate that around 90% of the Earths crust is made up of silicates. As silicon and oxygen are the
most abundant elements this is of no great surprise.

The basic chemical unit of silicates is the SiO4 tetrahedron. These tetrahedrons form a vast array of different structures across the mineral class. They can form as single or double units, chains, sheets, rings or frameworks.

The silicates used in polishing formulations are used as an ultrafine, delicate abrasive that are used for cleaning and polishing sensitive surfaces.

Aluminium Silicate in Polishing compounds

Aluminium silicate, in blends with other compounds, is supplied either in a paste or a liquid.

It is chiefly used in the auto trade for scratch removal, rubbing and polishing either by body shops or for pre sale renovation in the used car trade, but can also be found in retail products as well. Glazing compounds are often used after scratch removal.

Away from automotive applications aluminium silicate can be found in a wide range of cleaning and polishing applications such as hard and soft surface household and industrial cleaners and polishes, liquid cleaners and polishes for precious metals, all round retail products and hand cleaners.

Aluminium silicate in paints

Aluminium silicate is used in both domestic and industrial paints for a range of reasons.

- As a cost saver replacement for TiO2 without loss of opacity
- It is also used to increase thixotropy and so increase the non drip capacity of a paint
- It reduces the gravity settling of paints in storage and in situ
- It reduces drying time, and increases the abrasion resistance of the product

Aluminium silicate in rubber

- The large surface area of aluminium silicate helps it interact with the polymer.

- Aluminium silicate has low moisture, a stable pH, low oil absorbtion.

- It increases both tensile strength and resistance to tearing and abrasion as well as increasing hardness.

- It also imparts better ageing characteristics. Very useful in products such as shoe sole   rubber, tyres and gaskets amongst many other applications.
