July 16, 2025
[Problem]To provide an aqueous coating film-forming composition of the present invention that can be coated uniformly on a silicone rubber surface without causing repelling or coating failure even when applied in the silicone rubber surface at a film thickness of 30 µm or less, and forms an antifriction dry coating film that reduces friction and/or blocking of the substrate surface on the surface.[Resolution Means]An aqueous coating film-forming composition for forming an antifriction dry coating film that reduces friction and/or blocking of a surface of a substrate, containing (A) a solid lubricant, (B) a thickener, and (C) a silicone binder in the form of an oil-in-water silicone emulsion containing (c1) an ionic emulsifier and (c2) a polyoxyethylene-polyoxypropylene copolymerized nonionic emulsifier, where water content is removed to form an antifriction dry coating film containing 40 to 80 mass% the aforementioned component (A), 0.50 to 10 mass% of the aforementioned component (B), 0.60 to 5 mass% of the aforementioned component (c2), and 5 to 49.5 mass% of aforementioned component (C) (solid fraction); as well as an application thereof (particularly including airbag coating)
