摘要

AbstractThe emulsification and electrodeposition properties of two resins system (cationic epoxyamine adduct,III, was the main resin; nonionic trimethylolpropane–toluene diisocyanate‐2‐ethylhexanol resin,II, was used as cross‐linker) were investigated and the compositions of their electrodeposited films were obtained by Fourier transform infrared (FTIR) quantitative analysis to study the coemulsion and electrophoretic behaviors. The optimum resin compositionof coemulsion was also found to provide the deposited film having the best properties. The results indicate that the molecules of nonionic cross‐linkerIIare entangled by the ones of cationic resinIIIduring the dispersion process and they can be codeposited on the cathodic substrate after a voltage has been applied. Moreover, at the condition of stable coemulsion of the two‐component system, the resin composition of electrodeposited film is almost equal to the resin composition of the coemulsion and is not affected by the applied voltage or resin concentration. © 1993 John Wil
