Title:
WATER-BASED SURFACE TREATMENT AGENT
Document Type and Number:
WIPO Patent Application WO/2021/090628
Kind Code:
A1
Abstract:
A water-based surface treatment agent comprising (A) an aqueous emulsion of a silicone oil, (B) a silanol-modified polyurethane resin, (C) a silane compound and/or a product of partial hydrolysis thereof, (D) an aqueous emulsion of both a hydrazide and a carbonyl-group-containing polyurethane resin, and (E) an aqueous emulsion of a polyurethane resin which has a glass transition point of -30°C or lower and which, when heated with a flow tester from 40°C to 150°C at a heating rate of 5°C/min, shows a thermal softening temperature of 70°C or lower. This water-based surface treatment agent includes a silicone oil for preventing products from sticking to each other and a silanol-modified polyurethane resin binder having a low hardness and satisfactory adhesiveness to seal members, and improves the corrosion resistance of aluminum bases, etc.
