PPG's SunClean Windows are self-cleaning and contain an external thin film coating containing nanoparticles.
SunClean self-cleaning glass is a glass product with photocatalytic and hydrophilic properties that combine to result in windows that are easier to clean. The durable, transparent coating on SunClean self-cleaning glass is applied to hot glass during the formation process making it an integral part of the outer glass surface.
The photocatalytic properties of the glass coating are energized by UV rays to help slowly break down and loosen organic dirt.
The hydrophilic properties cause water to sheet evenly over the glass surface instead of beading. This sheeting action helps to flush the surface clean and to accelerate drying, leaving the glass with minimal spotting and streaking.
