Document Type and Number:

WIPO Patent Application WO/2007/026716

Kind Code:

A1

Abstract:

Disclosed is a stable aqueous surface treating agent for constructional/civil engineering structures which is able to impart a structure made of a constructional/civil engineering material such as stone and concrete, particularly one made of a porous material, with excellent water/oil repellency (water/oil proof property), antifouling property, weather resistance and durability. Specifically disclosed is an aqueous surface treating agent containing (A) at least one fluorine-containing polymer selected from (A1) polyfluoroalkyl group-containing poly(meth)acrylates and (A2) polyfluoroalkyl group-containing polyurethanes, in an aqueous medium. The aqueous surface treating agent usually contains (B) a surface active agent, and preferably contains (C) a silicone and (D) a silane compound having a hydrolyzable group and/or a partial hydrolysis-condensation product of a silane compound having a hydrolyzable group.
