Abstract:
A contamination-resistant float glass which comprises:a float glass comprising a top-side surface that has not been directly exposed to a molten tin bath and a bottom-side surface that has been directly exposed to a molten tin bath; anda contamination-resistant film, formed only on the top-side surface, the film comprising a molecule including a straight-chain of carbons, wherein the molecule is covalently bonded to the top-side surface via a siloxane bond,wherein the contamination-resistant film is formed by contacting a solution with the top-side surface only, using a roller coater, brush, a cast coater with a film, a doctor blade or a spin coater, the solution comprising a silane-based compound having a straight chain of carbons selected from the group consisting of silicon halogenide, silicon alkoxide and silicon isocyanide, and reacting the silane-based compound with a hydrophilic group on the top-side surface to bond a molecule including the straight chain of carbons to the top-side surface covalently via a siloxane bond.
