Abstract: A waterborne epoxy chromium corrosion protective primer for AA2024-T3 Al alloy was developed by using a self-emulsifying epoxy hardener and chromium -free anticorrosion pigment. Several influencing factors on the primer properties were discussed. The results demonstrated that this waterborne epoxy primer is a viable replacement for the currently used chromate -based primer and its performance is overpass the similar imported products.
