Photocurable cathodic electrocoating |
摘要 |
An electrocoating composition containing a polymer having pendant amine groups, a bis-maleimide crosslinking agent and an ultraviolet photosensitizer can be electrodeposited onto a cathode substrate disposed within an aqueous electrocoating bath. The amine groups of the polymer are protonated to render the polymer water dispersible prior to electrodeposition. Upon electrodeposition, the amine groups become de-protonated. The bis-maleimide crosslinks the polymer upon ultraviolet irradiation of the electrocoated cathode substrate to form a fully cured electrodeposited coating on the cathode substrate.
