Abstract

There is provided an aqueous coating agent composition that does not contain an organotin compound and forms a coating film having good slipperiness and having excellent adhesiveness (adhesion) and abrasion resistance. The aqueous coating agent composition contains: (A) polydiorganosiloxane having both terminals blocked with hydroxyl groups, the polydiorganosiloxane having a viscosity of 50 to 100,000,000 mPa·s (at 25° C.); (B) polyorganohydrogensiloxane having at least three hydrogen atoms in one molecule; (C) a zinc compound as a curing catalyst; (D) an organic compound and/or polyorganosiloxane having at least one of a primary amino group and a secondary amino group; (E) an adhesion improving component; and (F) spherical particles.
