Abstract:
Methods for producing 1,5,7-triazabicyclo[4.4.0]dec-5-ene using a disubstituted carbodiimide, dipropylene triamine and optionally an ethereal solvent and/or an alcohol are disclosed. Use of 1,5,7-triazabicyclo[4.4.0]dec-5-ene produced by this method in an electrodepositable coating composition, and electrophoretic deposition of such coating onto a substrate to form a coated substrate, are also disclosed.
Abstract:
An electrodepositable composition comprising: (a) an active hydrogen-containing, cationic salt group-containing resin, such as a (meth)acrylic sulfonium salt group-containing resin; (b) a capped polyisocyanate curing agent; and (c) a dialkyltin dicarboxylate or dimercaptide, in which one or both of the alkyl groups contain from 1 to 4 carbon atoms and one or both of the carboxylate and mercaptide groups contain from 8 to 12 carbon atoms.

Abstract:
The present invention relates to electrodepositable coating compositions that produce cured coatings that exhibit resistance to cratering. The coating compositions include an active hydrogen-containing cationic salt group-containing polymer; and 0.1 to 20 percent by weight, based on the total weight of resin solids in the coating composition, of an ungelled acrylic polymer.
Abstract:
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.
