Waterdispersible cationic resins for electrodeposition

摘要: Waterdispersible cationic resins are formed by reacting the components comprising at least (A) an epoxidized polydiene, (B) a bisglycidylether of polyphenol, (C) amide compound, which is one or more higher, substantially multiply unsaturated fatty acids and polyamine may comprise ketimine group hydroxy group, possibly (D) organic secondary amine and/or (E) partially fully masked polyisocyanate, product comprises excess epoxide groups carbon-carbon double bonds can be made waterdispersible with acid under formation groups. A composite provided resin superposed on conducting substrate method described for forming composite.
