MC-P5150 Color-Coated Metal Sheet Rust Inhibitor

Feature

  1. The rust inhibitor applied to dipping, spray and roller coating
  2. Contain hexavalent chromium and can increase anti corrosion of Galvanized sheet and alloy galvanized sheet

     

l Appearance: Greenyellow transparent liquid

l Density: 1.14±0.03 g/cm3

l Recommended concentration: 5-15%

l Solution Temperature: 20~40℃

l Chromic acid value: 11.5±1.5

l Dry temperature: 50~80℃

 

Adding 50~150L MC-P5150 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. 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

Supplement: Add 4.7L (5.3KG) MC-P5150 into 1000L solution while the chromic acid value decreases by 1
