SOCOSURF SCOP

• SOCOSURF TCS/SCOP is a two-part bath solution specifically developed to passivate and colour cadmium plated steel. SOCOSURF TCS is a trivalent chromium based passivation solution, to replace the current Cr(VI) passivation solution. 
• SOCOSURF SCOP is a solution to colour the layer to identify parts that have been passivated.
• SOCOSURF TCS/SCOP is developed from a patented technology.

Advantages / Benefits:  

• Colored layer: easy visual identification after treatment 
• Heat resistance 200°C: De-hydrogenation can be done after passivation 
• REACh compliance 
• Corrosion performance: no white corrosion at 96 Hr on cadmium plated steel (ISO 9227) and no red corrosion 750 Hr
