Epoxy sealing primer is composed of epoxy resin, polyamide resin, pigments, additives and solvents, etc.
Epoxy sealing primer is made according to the features of galvanized coating (zinc coating) and cold galvanized zinc coating. It is used as their sealing coating. and it has good adhesion of aluminum alloy and galvanized layer with appropriate surface treatment.
It can be used as sealing coating in metal aluminum coating layer and the metal zinc coating layer, and it has good permeability and sealing performance.
It can be well combined with zinc-rich primers such as inorganic zinc silicate primer, and it has good sealing performance.
Epoxy sealing primer is well resistant to alkali, and it can be used as sealing primer for external walls or floors.
And it has good interlayer adhesion with the paint film in latter procedures, and it can be used with a variety of anticorrosive paints.
Epoxy sealing primer is mainly used for galvanized coating (zinc coating) and sealing paint agent of cold galvanized zinc coating, and sealing coating of metal zinc coating layer, aluminum alloy coating layer, inorganic zinc-rich paint surface, and it also has very good permeability and closeness to the cement surface.
