Zinc Plated Clear Chromate Dip
Some of our metal finishes include anodizing chromating zinc plating electroless nickel plating tin plating wet paint and powder coating.
Zinc plated clear chromate dip. Advantages of clear zinc plating. It is similar to galvanizing. Overall people often choose clear zinc coating because it is both affordable and. An easy to use single dip trivalent iridescent yellow red bright chromate.
We can also improve the surface conditions of various metals with processes such as electropolishing passivation and bright dip. Meets automotive and all other industrial standards. A clear chromate dip is a protective film applied after electroplating adding corrosion protection. Zinc plated zinc chromate dichromate thanks very much.
The fix is a 0 5 nitric acid pre dip before the chromate use of a very blue trivalent chromate and close control of the chromate ph. With galvanized plating the result is typically 50 microns thick which therefore provides much more protection against corrosion. Zinc plating is an inorganic metal coating that is deposited on a steel using an external electric current. Zinc plating performs better than cadmium in an industrial atmosphere but not in a salt atmosphere.
Zinc electroplating is also a protective coating against corrosion blue gray in color non toxic and can be used around food. No additional top coat is required. P 1265 the coating serves as a corrosion inhibitor as a primer to improve the adherence of paints and adhesives as a decorative finish or to preserve electrical conductivity. Zinc plating with clear passivation gives all the same advantages of any other zinc plating particularly the addition of considerable corrosion resistance.
Zinc chromate is usually an organic primer paint that can be spray or brush applied over steel galvanizing or even zinc plating. Zinc plating with clear chromate has yellowish discoloration. Zinc plating is a popular choice for coating nuts bolts washers metal stampings automotive parts fabricated. With trivalent blue bright chromates increases in the ph that lead to values greater than 2 3 1 8 to 2 0 being optimal for most processes.
Offers high salt spray resistance of up to 200 250 hours to white rust. It also offers some benefits in terms of strength and abrasion resistance. Color is almost like hexavalent yellow. See more on zinc metal plating with zinc plating the coating is only typically 3 microns thick.
Yellow chromate a single dip trivalent yellow chromate.
