Feature

Non chromium corrosion inhibitor

No effect on the glossy of copper

Can increase the copper material anti-corrosion performance


Application process


  • Appearance: Yellow green transparent liquid
  • Recommended dosage: 10%
  • Applied Temperature: 50~60℃
  • Processing way: Dipping, or spray


1. Adding 50~150L MC-P5560 and 850~950L deionized water or soft water into 1000L tank. The chromic acid value is 10.4~31.3 in the aqueous. 

Chromic acid value test method: Firstly, add 10ml aqueous into an Erlenmeyer flask. 

2. Then add 50ml DI water and 20ml 50% H2SO4 aqueous. Add 1~2g KI follow. Using 0.1mol/L Na2S2O3 standard solution to titrate it. While the solution changes from reddish brown to yellowish-brown, add 2ml starch solution. The solution turns into dark blue. Then continue to use 0.1mol/L Na2S2O3 standard solution to titrate till dark blue disappears. The consumption volume of 0.1mol/L Na2S2O3 standard solution is the chromic acid value

3. Supplement: Add 4.7L (5.3KG) MC-P5560 into 1000L solution while the chromic acid value decreases by 1.

Note: Must wear safety glasses, rubber gloves and protective clothing of chemical pollution, avoid contact with skin, do not inhale vapors.


Technical process

① Clean---②Water wash---③Water wash---④Air dry---⑤MC-P5560 dipping/spray---⑥dry

Remark: 1. The steel temperature: 50~80℃. 2. While spraying 3ml/m2 on the sheet surface, it can produce 10~28 mg/m2 anti-corrosion layer.


Application

-Cast iron parts, cold-rolled sheet and galvanized steel profiles surface treatment etc.


Storage and handling
