摘要
In the present study, a grafted acrylic-epoxy polymer coating has been developed for cathodic electrodeposition. This is a mono-coat system where different colours (red, blue, black, grey, etc.) are developed in electrodeposition coatings. In this research, the mono-coat technology provides the dual coat (primer and overcoat). The mono-coat electrodeposition system has several advantages compared to conventional electrodeposition such as excellent durability, better UV resistance (500 h), lower cost in paint application and better metal protection against corrosion (500 h salt spray test as per ASTM B 117). The discussion would highlight the formulation concept and mechanism of electrodeposition coatings. The polymers of the grafted acrylic-epoxy system have been developed by varying the grafted acrylic/epoxy ratio. The grafted acrylic/epoxy composition of 80:20 has been found to have optimum anticorrosive and UV resistance properties.
