Study of Anti-corrosion Performance of Primer in Water Environment

Five kinds of common anti-corrosion primer were chosen as samples to test the anti-corrosion and other performance in water environment.The anti-corrosion performance was studied.The results showed that epoxy primer and high-chloride primer have certain water resistance;alkyd primer has poor water resistance;zinc-rich primer has cathodic protection effect and better water resistance;Organic coating has better corrosion resistance in the Salt Lake water medium.
