[Product Description]

Based on nanoparticles, combined with a specific treatment of silane, a new composite technology is used. On a clean metal surface, rapid adsorption bonding forms a special hydrophobic silane polymer coating. The silane agent improves the adhesion between the metal and the coating (the cross-linking of silane and the resin) and enhances the corrosion resistance of the coating (the special hydrophobic silane layer).

[Performance Characteristics]

☆ No phosphate, heavy metals; Compared with chromium passivation and without chromium passivation, no sediment, low dose chemical consumption; Simple wastewater treatment

☆ Less pharmaceutical consumption, each kilogram of pharmaceutical can handle about 20000 ~ 60000 square meters; The film can be formed in 2-5 seconds, the process is short, and the new line construction cost is low; Fast degradation, low waste water treatment costs

☆ Strong coating adhesion to aluminum, magnesium and zinc alloys; Acid and alkali resistance test and Machu filamentous corrosion, surface and incision are not peeling phenomenon of good wet adhesion, boiling water for 2 hours, 100 grid adhesion level 0; Fast impact deformation test and 0 degree bending test, no falling off and stripping

[Scope of application]

It is suitable for the pretreatment process of various types and thicknesses of aluminum coils.
