Finally, a Valid Use for Titanium
06/02/04
Good old, Ti, poster material for "Value Added" electronics has gained a dubious reputation over the past few years. Practically the only technology overused more in design contests is Bluetooth, even though the benefits gained from the metal are minimal. But now, a total of four companies - Pilkington, PPG, Asahi Glass Co., and Saint Gobain - have developed titanium dioxide photocatalytic coatings for glass which allow the glass to be self cleaning, and non fogging. The coating works with UV light to break down oils that cause dirt to build up on surfaces, while also allowing water to sheet on the glass to clean the deposits away. Check out a more in-depth explanation of TiO2's properties here. The coating has the potential to eliminates thousands of pounds of yearly phosphate load in streams from detergents used in window washing. We just want to see this as a coating for car paint and driveways. We're tired of fingerprints and oil stains.
