The Zinc Al Flake coating offers excellent protection from mechanical and chemical impact. Protection against contact corrosion is enhanced and abrasion resistance is clearly increased. Integrated dry films lubricants help achieve defined friction coefficients.
Generally, for the Zinc Flake coatings, the coating thickness ranges from 5-15 microns. The corrosion resistance can be achieved over 1000 hours by ASTM B117 in Salt Spray test; The results of corrosion depends upon the shape and geometry of the parts. Other properties of the zinc flake coatings are Water soluble: Low VOC, Sacrificial behavior, Heat resistance of 150 c by organic and 200 c by Inorganic sealer top coats, Free from Hydrogen Embrittlement, Protection of various corrosions, Anti Freezing in cold climates, High Chemical resistance, Improved Wear resistance, Colored sealer top coats for aesthetic and sorting, Possible to adjust the required Co-efficient of friction to reduce noise level, No hydrogen Embrittlement stress cracking of high strength and spring steel kind of metal parts.
Zinc Al Flake coating technology can be a direct replacement of Electrolytic ( Electroplating ) and Galvanic (Hot Dip Galvanizing) coating finishes in respect of enhanced corrosion properties, Hydrogen Embrittlement free, longer coated product life and environmental friendly nature during its application processing.
