Surface treatment agents and items treated with surface treatment agents.

Abstract

The invention relates to a product that is a surface treatment with excellent storage stability under all temperature conditions, especially in high-temperature environments. The product offered is also an article treated with this surface treatment. The surface treatment consists of (A) a hydrolyzable silane modified by a polymer containing a fluoropolyether group and / or a partially hydrolyzable silane condenser; and (B) a fluorine-containing solvent, wherein the fluorine-containing solvent (B) contains fluoride ions in an amount greater than 0% by mass and not more than 1.0 x 10⁻⁵% by mass based on the total amount of the surface treatment.
