ABSTRACT:
Method for producing novel photochemically-active metal oxide-containing aqueous compositions such as TiO2compositions coated or sprayed and dried under ambient conditions to form novel photochemically-active, colorless coatings having strong wetability and adhesion to clear substrates such as window glass. Preferably the present compositions include a suitable wetting agent or combination of agents to improve the wetability of the Titanium peroxide-containing amorphous film, allowing thinner films to be readily applied. Also the inclusion of an acrylic aliphatic urethane polymer can replace wholly or partially the titanium peroxide sol and provide additional film forming and wetability properties. The acrylic urethane polymer reduces or eliminates the amount of titanyl peroxide that is required and thereby reduces or eliminates the yellow color.
