摘要： An aqueous surface-treating agent comprising (A) an aqueous emulsion of silicone oil, (B) a silanol-modified polyurethane resin, (C) a silane compound and/or a partial hydrolysate thereof, (D) an aqueous emulsion of a hydrazide and a carbonyl group-containing polyurethane resin, and (E) an aqueous emulsion of a polyurethane resin having a glass transition temperature of −30° C. or lower, and a thermal softening temperature of 70° C. or lower measured by using a flow tester when heated from 40° C. to 150° C. at a heating rate of 5° C./min. The aqueous surface-treating agent contains silicone oil for preventing sticking between products and a silanol-modified polyurethane resin binder having a low hardness and excellent adhesiveness to seal members, and improves the corrosion resistance of an aqueous surface-treating agent for aluminum substrates etc.
