Abstract

Two kinds of cathodic electrophoretic coatings were synthesized.One is the cathodic electrophoretic coating with oxazolidone structure,and the other is the cathodic electrophoretic coating synthesized by conventional route.The prepared cathodic electrophoretic coating with oxazolidone structure can effectively improve the high temperature heat-resistant yellowing and UV irradiation decomposition of electrophoretic coating,increase the toughness,have better corrosion resistance,and have good appearance and excellent performance indexes.

Key words

epoxy cathodic electrodepostiton coatings;oxazolidone;heat-yellowing resistance;weather resistance;salt spray resistance performance
