摘要： PURPOSE:To form a multilayer coating film by successively applying intercoat paint and topcoat paint composed of a resin containing a specific hydrolyzable group and an epoxy group or further containing a hydroxyl group to a cation electrodeposition coating surface of a specific composition. CONSTITUTION:Cation electrodeposition paint based on a resin having a hydroxyl group and a cationic group and an epoxy resin having two or more functional groups, wherein epoxy groups are bonded to an alicylic skeletal, per one molecule thereof on an average is applied. Subsequently, intercoat paint and topcoat paint are successively applied to the formed painting surface. In this case, as either one of or both of the intercoat paint and the topcoat paint, paint based on a resin composition containing a hydrolyzable group directly bonded to a hydroxysilane group and/or a silicon atom and an epoxy group or further containing a hydroxyl group if desired as essential functional group components is used.

摘要： PURPOSE:To obtain the subject coating with no environmental pollution without using any toxic metal compd. and excellent corrosion-proof properties and smoothness by compounding a specified amt. of an iron oxide in a cationic electrodeposition coating. CONSTITUTION:The subject coating is obtd. by compounding 3 to 50wt.% iron oxide based on the total amt. of the resin in a cationic electrodeposition coating. By said method of compounding an appropriate amt. of the iron oxide, the curing of a resin in the electrodeposition coating is accelerated and the formation of a coating is completed at a lower temp. in a shorter time and the surface of the coating is made denser. Excellent corrosion-proof properties can b e thereby obtd. without using any toxic metal compd. such as a lead or chromium compd. In addition, there is no possibility of contamination of a drain with the toxic metal compd., so that the environmental pollution can be prevented.
