SURFACE TREATMENT COMPOSITION, METHOD OF SURFACE TREATMENT, SUBSTRATE, AND ARTICLE

摘要

A surface treatment composition excellent in storage stability and waterdrop repellency. The composition comprises as the essential ingredient partial hydrolyzates of a reactive fluorosilane, such as C8F17CH2CH2Si(OCH3)3, which have a molecular weight of M as measured by GPC, and in which the content of partial hydrolyzates having a molecular weight in the range of 300 to 2M is below 70 % and that of partial hydrolyzates having a molecular weight in the range of 6M to 100,000 is below 10 %. The method of surface treatment comprises treating a surface of a glass with the surface treatment composition. The substrate is one treated with the surface treatment composition. The article, e.g., one for transport apparatus, contains the substrate fitted thereto.
