Performance Everyday. Tin-oxide coatings keep glass freezer doors frost-free for unobstructed viewing. Similar tin-oxide coatings also perform a vital safety function on oven doors by lowering the temperature of the glass surface, thereby reducing the possibility of burns. Other applications such as computer and TV screens, flat panel displays, and fluorescent lights benefit from the transparency, conductivity and durability of these coatings. Effectcoat™ Spray Glass Coatings and Certincoat® CVD Coatings can help provide this vital performance.
