Pilkington Activ™ self-cleaning glass
Pilkington Activ™ is the world's first pyrolytic self-cleaning glass. This revolutionary kind of glass actually uses the power of the sun to clean itself.
The Pilkington Activ™ coating is applied to the surface of the glass via an on-line chemical vapour deposition process. It is an integral part of the surface, and lasts the entire life of the glass.
Pilkington Activ™ uses daylight, which is abundant even on cloudy days, to keep glass clean with a two-step process:
1) Pilkington Activ™ loosens dirt, and gradually breaks down organic residue using energy from daylight.
2) The hydrophilic nature of the Pilkington Activ™ coating allows water to sheet off its surface, removing organic residue, dust particles and inorganic dirt.
Under most conditions, natural rain is sufficient to keep the glass clean but use of a hose will achieve the same result.
In addition to providing an easy to clean surface, the Pilkington Activ™ range is also oleophobic, acting as an anti-fingerprint coating. The photodecomposition properties of Pilkington Activ™ break down organic contaminants, e.g. stearic acid, acetone or paraffin wax. Pilkington Activ™ can also contribute to the destruction of bacteria and ozone.
Available in large sizes, up to 6000 x 3210 mm, and glass thicknesses of 3 mm to 10 mm.
