Silica sand is a major ingredient in the production of glassmaking in fact, silica is the primary component in standard glass products ranging from windows to bottles. The purity of the silica sand used plays a role in determining the colour, strength and clarity of the final product.
The most common form of SiO2 is quartz a chemically inert and relatively hard mineral. SiO2 grades at a 7 out of 10 on Mohs hardness scale, making it ideal for use as filtration media and abrasive blasting sands.

Each paint is designed with specific attributes in mind, and Nanosil Series Silica is one of the ingredients that allows for each specificity. Nanosil Series Silica functions in paints and coatings as a great low-cost extender. As in other applications, Nanosil Series Silica is desirable for its chemical inertness which allows for good acid, chemical, and heat resistance. In marine and maintenance coatings, the durability of Nanosil Series Silica imparts excellent abrasion and corrosion resistance.

1. Nanosil Silica’s low oil absorption allows increased pigment loading for improved finish color.
2. Along with its chemical inertness, Nanosil Silica's hardness improves abrasion resistance in paints.
3. Paint formulators select micron-sized industrial sands to improve the appearance and durability of architectural and industrial paint and coatings.
4. In architectural paints, Nanosil Silica fillers improve tint retention durability, and resistance to dirt, mildew, cracking and weathering.
5. Nanosil Silica’s low oil absorption allows increased pigment loading for improved finish color.
6. In marine and maintenance coatings, the durability of Nanosil Silica imparts excellent abrasion and corrosion resistance.
7. Nanosil Silica improves the most important qualities in paints such as reflectance, brightness and color consistency for any large scale uses. Industrial sand, therefore, plays a role in keeping the buildings, cars, and boats we see from looking worn or dingy.

Fumed silica (CAS number 112945-52-5), also known as pyrogenic silica because it is produced in a flame, consists of microscopic droplets of amorphous silica fused into branched, chainlike, three-dimensional secondary particles which then agglomerate into tertiary particles. The resulting powder has an extremely low bulk density and high surface area. Its three-dimensional structure results in viscosity-increasing, thixotropic behavior when used as a thickener or reinforcing filler.
Fumed silica has a very strong thickening effect. Primary particle size is 550 nm. The particles are non-porous and have a surface area of 50600 m2/g. The density is 160190 kg/m3.
