Abstract: A kind of waterborne anti-corrosive organic zinc-rich primer is formulated, with waterborne acrylic resin as the main film-former, compounded with spherical zinc and flake zine powders. The factors which had influences on the anti-corrosive performance of zinc-rich primer were analyzed. The results showed that when emulsion A as the main film-former, spherical zinc 2^# (800 mesh) with the ratio of flake zinc I as 3: 2, pigment 6% and PVC 50% -55%, the comprehensive performances is the best.
