What are the advantages of Dacromet bolts? Dacromet is a new type of surface treatment technology. Compared with the traditional electroplating process, Dacromet is a "green plating".
1. Superior corrosion resistance: Dacromet film thickness is only 4-8μm, but its antirust effect is
Rhenium is more than 7-10 times of the traditional galvanizing, hot-dip galvanizing or coating method. The standard parts and pipe fittings processed by Dacromet process did not show red rust for more than 1200 hours after the salt spray test.
2. Hydrogen-free embrittlement: Dacromet's treatment process determines that Dacromet does not have hydrogen embrittlement, so Dacromet is very suitable for load-bearing parts.
3. High heat resistance: Dacromet can withstand high temperature corrosion, and the heat resistance temperature can reach above 300 ℃. In the traditional galvanizing process, the skin is scrapped when the temperature reaches 100 ° C.
4. Good adhesion and recoating performance: Dacromet coating has good adhesion to the metal substrate, and has strong adhesion to other additional coatings. The treated parts are easy to spray and color, and are combined with organic coatings. The force even exceeds the phosphate film.
