Japanese Patent JP2525621
Kind Code:
B2
Abstract:
This invention provides a process for the preparation of water-thinnable, hydrolytically stable, thermosetting, cationic coating composition, which comprises blending: 1) 5-35 %w of a crosslinking compound, and 2) 65-95 %w of a carboxylated amide group-containing amino binder being the reaction product of an amino group-containing resin binder and not more than 0.1 mol of a cyclic anhydride per amino group equivalent of said amino group-containing resin binder, which amino group-containing binder comprises the reaction product of a) ammonia, and b) a blend of b1) a polyglycidyl ether having n epoxy groups per molecule, wherein 12, and (x-n) mol of a monofunctional phenol per mol of the multifunctional polyglycidyl ether, and b2) a diglycidyl ether, having an EGC in the range of from 1000 to 5500 mmol/kg, the average molar epoxy functionality of the glycidyl ethers present in the blend of polyglycidyl ehter and diglycidyl ether being <1.75. and wherein 1) and 2) are blended before or after neutralization of 2). The thus prepared coating compositions when used for coating the interior of food and beverage cans, result in coatings which combine very good taste performance properties with a high level of mechanical and chemical resistance properties.
