Abstract

The invention provides a fluorinated coating composition which can stably form a uniform coating film on a substrate and the storage stability is improved when a former solution is used, and an article treated with said coating composition. The fluorinated coating composition is characterized in that in the coating composition containing the following components (A) -(C), the content of the (A) component is 0.01-50 mass% relative to the whole coating composition, and the content of the (C) component is 0.01-5mass% relative to the whole coating composition. The (A) component is a silane containing a hydrolysis group and/or a partial hydrolysis condensation compound, and the silane is modified by a polymer containing a fluoropolyether group. The (B) component is the solvent which can uniformly dissolve the (A) component, and the (C) component is a silanization compound with molecular weight less than 250 and the hydrolysis group.

Description

technical field [0001] The present invention relates to a coating agent containing a hydrolyzable group-containing silane modified with a polymer containing a fluoropolyether group and / or a partially hydrolyzed condensate thereof, and specifically relates to storage stability in a solution state before use It can stably form a uniform coating film on the substrate, form a coating film with excellent water and oil repellency, and low dynamic friction while improving and / or a fluorine-containing coating agent of a partially hydrolyzed condensate thereof, and articles treated with the coating agent. Background technique [0002] In recent years, touch panelization of screens has been accelerated, including displays for mobile phones. However, the screen of the touch panel is often exposed, and there are many opportunities for direct contact with fingers, cheeks, etc., and dirt such as sebum is easy to adhere to, which has become a problem. Therefore, in order to improve the a...
