Dacromet Coating Bolt

 Dacromet Coating Bolt

In the standards of Dacromet in our country, called "Zinc/Chromate Coatings" is a metal coating treatment technology similar to electric galvanizing. Dacrosol coating appearance is silver gray, the coating contains 80% of thin zinc and aluminum, the rest are chromate, has excellent properties, such as strong corrosion resistance, is 7-10 times higher than electrogalvanizing; No hydrogen embrittlement; Especially suitable for high-strength stress parts such as high-strength bolts used in subway projects; High heat resistance:Heat resistant temperature 300°C. In addition, it also has the advantages of high permeability, high adhesion, high wear resistance, high weather resistance, high chemical resistance stability and no environmental pollution.
