Title:
ELECTRODEPOSITION COATING COMPOSITION AND ELECTRODEPOSITION COATING METHOD
Document Type and Number:
WIPO Patent Application WO/2015/146480
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide an electrodeposition coating composition which exhibits excellent throwing power and enables the achievement of a cured electrodeposition coating film having good appearance; and an electrodeposition coating method. An electrodeposition coating composition according to the present invention contains at least one compound (A) selected from the group consisting of zinc compounds (A-1) and bismuth compounds (A-2), an aminated resin (B) and a curing agent (C). The milligram equivalent (MEQ (A)) of an acid per 100 g of the resin solid content in the electrodeposition coating composition is 27 or more. The coulombic efficiency of the electrodeposition coating composition is 30 mg/C or less. An uncured electrodeposition coating film formed using this electrodeposition coating composition and having a thickness of 15 μm has a film resistance of 400 kΩ·cm2 or more. An electrodeposition coating film obtained from this electrodeposition coating composition has a coating film viscosity of 3,000 Pa·s or less at 50°C.
