The traditional galvanizing process, the temperature reached 100 ℃ when the skin has been scrapped. 2. Super corrosion resistance: Dacromet film thickness of only 4-8μm, but its anti-rust effect is the traditional electro-galvanized, hot-dip galvanized or coating coating method more than 7-10 times. Dacromet process using the standard parts, pipe fittings by salt spray test 1200h or more did not appear red rust. 3. Good permeability: Due to the electrostatic shielding effect, the workpiece deep hole, slit, pipe wall and other parts of the hard to electroplate the zinc, so the workpiece can not use the location of the protection method. Dacromet can enter these parts of the workpiece to form Dacromet coating. 4. Hydrogen free brittleness: Dacromet treatment process determines the Dacromet no hydrogen embrittlement phenomenon, so Dacromet is very suitable for the force of the coating. 5. Adhesion and re-coating performance: Dacromet coating and metal matrix has a good binding force, and with other additional coating has a strong adhesion, the treated parts easy to spray coloring, combined with the organic coating Force even more than the phosphate film.
