Abstract:
An all-blocked isocyanate with oxazolidone groups was prepared which was used as crosslinker for electrodeposition coatings. The structures and properties of the curing agent were characterized by fourier transfer infrared (FT-IR) and thermogravimetric analysis (TGA). The epoxy cathodic electrodeposition coatings based on this curing agent presented a good heat -yellowing resistance, better appearance and excellent performance.
Key words:
