Organo-metal oxide chelates stable in aqueous compositions are provided by the reaction of metal alkoxide-where the metal is titanium, zinc, tungsten, or tin-and a polyalkylene glycol. Specific compounds are the reaction product of tetra alkyl titanates with diethylene glycol. Aqueous coating compositions containing the chelates may be applied to fiber glass at the filament stage or after forming into mats. When heat treated, the coated fiber glass serves as photocatalytic media. |
