Abstract
A method of coating a glass surface with a heat-reflecting titanium oxide film, which may optionally comprise other metal oxide(s), by thermal decomposition of a titanium compound contained in a solution applied onto the glass surface. The coating is achieved with improved heat reflectivity and adhesion strength by using an organic solvent solution comprising a chelated titanium compound having at least one propoxy group or butoxy group and at least one octyleneglycol chelate ligand.
Claims11
In a method of coating a glass surface with a heat-reflecting metal oxide film, which comprises titanium oxide as an essential component thereof, by applying a solution containing a thermally decomposable titanium compound dissolved in an organic solvent onto a surface of a glass body and heating the solution on the glass surface to cause thermal decomposition of the titanium compound to titanium oxide,
- the improvement comprising the use of a chelated titanium compound as said thermally decomposable titanium compound, said chelated titanium compound having at least one alkoxy group selected from the group consisting of propoxy groups and butoxy groups and at least one octyleneglycol chelate ligand.
In a method of coating a glass surface with a heat-reflecting metal oxide film, which comprises titanium oxide as an essential component thereof, by spraying a solution containing a thermally decomposable titanium compound dissolved in an organic solvent onto a surface of a glass body which has been heated in advance so that said surface is maintained at a temperature sufficient to cause thermal decomposition of the titanium compound to titanium oxide,
- the improvement comprising the use of a chelated titanium compound as said thermally decomposable titanium compound, said chelated titanium compound having at least one alkoxy group selected from the group consisting of propoxy groups and butoxy groups and at least one octyleneglycol chelate ligand.
