The formula composition,product performance and application process of a new water-based epoxy primer for the railway vehicle were introduced. The water-based epoxy primer was prepared by using water-based epoxy resin and water thinned polyamine adduct as the film forming matter,antirust pigment without heavy metal ions,talcum powder and precipitated barium sulphate as the pigments and fillers,nano zinc oxide as the modified materials, matching with a variety of functional additives and water. The film was environmental friendly,and it had excellent adhesion and corrosion resistance,and matching well with common polyester putty/modified polyester putty,water-based acrylic polyurethane primer surfacer and water-based acrylic polyurethane top coat for the railway vehicle.
