Abstract: The present invention relates to a photocatalytic coating film composition and method for producing thereof. More specifically, it relates to an acidic anti-mould and anti-fungal photocatalytic coating film formed by the decomposition and evaporation of the volatile organic base from the photocatalytic coating composition after the application and the drying on substrate. The photocatalytic coating liquid composition consisting of a strong acidic nature of Nafion with pH<2 as an indispensable binder resin; a volatile organic base to neutralize the acidic binder resin temporarily and photocatalysts to generate strong oxidizing compounds which decompose harmful organic compounds and also to provide protection for the acidic environment by decomposing neutralizing chemicals from outside.

Abstract: The present invention is related to a thermo-shielding window coating composition having improved thermo-shielding and weathering resistant properties when applied to glass surfaces. The composition is made by first mixing an infrared absorbing pigment in amount of up to 5 wt. % with first dosage of an aqueous or alcoholic sulfonate group grafted fluoropolymer resin in amount of up to 10 wt. %, and water in amount of up to 10 wt. % to obtain a mixer, then dispersing the mixer by a disperser, and simultaneously adding second dosage of the sulfonate group grafted fluoropolymer resin in amount up to 90 wt. % to the above mixer until homogenous solution is obtained, wherein the weight % is calculated based on the total weight of the coating composition.
