The water-based aluminum silver paste adopts the advanced foreign organic silica coating technology, adsorbs a layer of anti-corrosion, acid-base dense adsorption film on the surface of aluminum ions, and additionally coats a protective layer of polymer twice. The thickness of the coating is dense and uniform, and the contact between oxygen and water is ensured to ensure that the aluminum pigment does not generate gas, is easy to store, has good compatibility and weather resistance, is easily dispersed and arranged in an aqueous system, and the resin is cured. A smooth, scintillating surface finish and an excellent metallic feel are obtained.
