Abstract
A coating agent is disclosed, which is suitable for concrete structures. The coating agent comprises: (A) a diorganopolysiloxane capped at both molecular terminals with silanol groups or silicon atom-bonded hydrolyzable groups; (B) a silane compound having at least two silicon atom-bonded hydrolyzable groups per molecule, or a partially hydrolyzed condensate thereof; (C) a curing catalyst; and (D) fumed silica. The coating agent forms a silicone film that is strongly adherent to a concrete structure, and that enables visual confirmation of the surface state of the concrete structure through the silicone film.
