METHOD FOR COATING PIPE SEGMENTS

摘要

A method for coating a segment of pipe is disclosed. The method comprises applying by electrodeposition a coating composition to the segment of pipe wherein the coating composition comprises: (i) a (meth)acrylic polymer dispersed in aqueous medium prepared by polymerizing in the presence of a cationic salt group containing polymeric dispersant a polymerizable ethylenically unsaturated monomer composition comprising a mixture of ethylenically unsaturated monomers at least one of which contains at least two ethylenically unsaturated groups per molecule; (ii) an electrodepositable cationic resinous vehicle containing active hydrogen groups; and (iii) a curing agent reactive with the active hydrogen groups.
