Title:
AMINE-MODIFIED EPOXY RESIN AND CATIONIC ELECTRODEPOSITION COATING COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2017/038631
Kind Code:
A1
Abstract:
[Problem] To provide a cationic electrodeposition coating composition containing an amine-modified epoxy resin which achieves sufficient throwing power and corrosion resistance even in the case of being less than 1000 μS/cm, and has excellent emulsion stability. [Solution] The cationic electrodeposition coating composition is characterized in that a resin emulsion contains: an amino group-modified epoxy resin (A) obtained by reacting, with an amine compound (A2), an epoxy group of an epoxy resin (A1) obtained by reacting a propylene oxide-added diepoxy resin (a1) having a specific structure, a bisphenol compound (a2), a diepoxy resin (a3), and a dicarboxylic acid (a4) having two carboxyl groups bonded together by at least one carbon atom; and a curing agent (B) which can cross-link the amino group-modified epoxy resin (A).
