Abstract
PURPOSE: A water-born coating composition that contains a specific water-soluble or dispersible resin has desirable properties required as a cathod precipitating type electrocoating and gives coating films with high impact strength, anticorrosion, water resistance and hardness.
CONSTITUTION: After the epoxidation of a liquid polybutadiene with a number average molecular weight of 500W5,000, an iodine value of 100W500, and a 1,4- linkage content of over 30 %, by hydrogen peroxide or a peracid to an epoxidized butadiene with an oxirane oxygent content of 1,5W13 wt%, the epoxy rings are opened by the reaction with an amine bearing primary or secondary amino groups. Then the resulting polymer is treated with an acid or a halogenated alkyl to form a water- soluble or dispersible resin, which is made into a 5W60 wt% aqueous solution or dispersion. Finally, 100 parts by wt of the water dispersion is mixed with 400 parts or less amount of pigments.
