摘要： PROBLEM TO BE SOLVED: To provide a maintenance method by a self-washing for a window glass which does not get wet with rain. SOLUTION: On the window glass 1, an ultra-hydrophilic surface treatment wherein a contact angle becomes less than 10 deg. is applied. Then, a sealing material on the outdoor side for a sash attaching section of the window glass 1 is constituted of an irregular sealing material wherein water-repellent components do not elute, or of a regular gasket 3 without the elution of water- repellent components. In addition, at both ends of a sash lower frame 2a, a drip 5, which has water returning mechanisms 5a and 5b such as a rising dam, and projects from an external wall by a specified amount, is provided. Then, cold air is jetted from the inside of the glass surface, and condensation is generated on the glass external surface. Thus, a water film is formed on the total surface, and dust and dirt are washed away.

摘要： PROBLEM TO BE SOLVED: To provide a point composition capable of realizing excellent weather resistance as well as imparting excellent low pollution properties by making a film surface layer section hydrophilic in a short time after painting. SOLUTION: The paint composition with low pollution comprises a tetraalkoxysilane and/or its partially hydrolyzed condensation product, a paint vehicle resin, and a porous polymer coating photocatalyst. By comprising the porous polymer coating photocatalyst (e.g. porous silica coating titanium dioxide), a hydrolysis of an alkoxysilyl group to a silanol group is accelerated, and weather resistance of the film is imparted because decomposition of the paint vehicle resin is far controlled compared to using untreated titanium dioxide. Further, by comprising a light screening pigment (e.g. titanium dioxide for a pigment), an UV screening effect is imparted, and decomposition of the paint vehicle resin is controlled, and the weather resistance is more and more improved.
