- Chemical Family
- Silica
AL FS 800 is hydrophilic fumed silica surface treated with polydimethylsiloxane to make it hydrophobic. Fumed silica’s unique manufacturing process produces a very high purity type of silica with nano size primary particles, a fluffy white powder that is an amorphous and colloidal form of silica. These characteristics impart a wide range of benefits to formulations from thickening and reinforcement to free flow and anti-settling. In addition the treatment imparts added water repellency, corrosion resistance, as well as thickening of complex polar liquids
