1. Good corrosion resistance: Xinxiang Dacromet coating film thickness is only 4-8μm, but its anti-rust effect is more than 7-10 times that of traditional electro-galvanizing, hot-dip galvanizing or paint coating methods. The standard parts treated with Dacromet process, the pipe joints have passed the salt spray resistance test for more than 1200h without red rust.
2. No hydrogen embrittlement: Dacromet's treatment process determines that Dacromet has no hydrogen embrittlement phenomenon, so Dacromet is very suitable for coating of stressed parts.
3. High heat resistance: Xinxiang Dacromet coating can resist high temperature corrosion, and the heat resistance temperature can reach more than 300 degrees Celsius.
4. Good adhesion and recoating performance: Dacromet coating has good adhesion to the metal substrate, and has strong adhesion with other additional coatings. The treated parts are easy to spray and color, and the combination with organic coatings The strength even exceeds that of phosphating film.
5. Good permeability: Due to the electrostatic effect, it is difficult to electroplate zinc on the deep holes, slits, inner walls of pipe fittings and other parts of the workpiece, so the above parts of the workpiece cannot be protected by electroplating. Dacromet can enter the workpiece These parts form a Dacromet coating.
6. Reduce processing cost.
