Abstract

There is disclosed a fluorine-based surface treating agent for vapor deposition comprising (A) a hydrolyzable group-containing silane modified with a polymer containing a fluorooxyalkylene group and / or a partial hydrolytic condensate, and (B) a polymer containing a fluorooxyalkylene group having a higher weight average molecular weight than component (A), wherein components (A) and (B) are mixed in a weight ratio of from 6:4 to 9:1.

Description

technical field [0001] The present invention relates to a surface treatment agent comprising a silane modified with a polymer containing fluorine oxyalkylene groups. More particularly, the present invention relates to a surface treatment agent capable of forming a coating film having excellent hydrophobicity and oleophobicity and a low coefficient of dynamic friction, and to an article modified with the surface treatment agent. The surface treatment agent of the present invention is composed of silane modified with a fluorine-containing oxyalkylene group polymer and / or its partial hydrolysis condensate, and a fluorine-containing oxyalkylene group polymer having a higher weight-average molecular weight in a specific ratio. Background technique [0002] Recently, there has been an accelerating trend in which displays of mobile phones are replaced by touch screens. Disadvantageously, since the touch screen type display is usually exposed and subjected to direct contact with us...
