Through the use and selection of resin,aluminum silver paste and additives,the silver powder was uniformly fixed.The stability,durability,fullness and chemical resistance of the product were improved,and the product had good weather resistance and mechanical properties.The coating was used as the topcoat of galvanized parts,and was matched with cold zinc coating,so that the plating layer achieved the same effect as hot-dip galvanizing.The process operation is simpler and more efficient,which simplifies the hot-dip galvanizing construction process,reduces energy consumption and pollution,and can be widely used in metal protection,industrial corrosion prevention and other fields.
