Title:
CATIONIC ELECTRODEPOSITION COATING COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2016/143707
Kind Code:
A1
Abstract:
The objective of the present invention is to provide a cationic electrodeposition coating composition containing a bismuth compound, which provides a cured electrodeposition coating film that exhibits excellent coating film appearance, impact resistance, corrosion resistance and the like.
The present invention provides a cationic electrodeposition coating composition which contains an aminated resin (A), a blocked isocyanate curing agent (B), an aminopolyether-modified polyalkylene glycol resin (G) and a pigment-dispersed paste, and wherein: the pigment-dispersed paste is obtained by preparing a bismuth mixture (C) by mixing a bismuth compound (c1) and an organic acid (c2) in advance, and then mixing the thus-obtained bismuth mixture (C) with a pigment-dispersed resin (D) and a pigment (F); the pigment (F) contains zinc oxide in an amount within the range of 0.5-5% by mass; and the aminopolyether-modified polyalkylene glycol resin (G) is a resin that is obtained by reacting an aminopolyether with a polyalkylene glycol diglycidyl ether.
