Non-phosphate rust inhibitor and protective film for sheet and aluminum MC-FM7010

Feature

Non VOC and non-phosphate reactive product

Can increase the coating adhesion and anti-corrosion performance

Excellent corrosion resistant comparable with zinc phosphating

Application process

Appearance: Yellowish liquid

Recommended dosage: 3% (EDTA value is 6.0 pt)

Temperature: Room temperature

Processing time: 1-3 min

Spray pressure: 0.06~0.15MPa

pH: 4.4-5.4

Normally add 30 kg MC-FM7010 in 1000 L water at the beginning. Then add the additive-001 and additive-002 to regulate the pH to the optimal value.

1. EDTA value test method: Firstly, add 10ml aqueous into an Erlenmeyer flask. Then add 20ml WL-A and 5ml 5% hydroxylamine hydrochloride aqueous. Thirdly, add 0.05-0.1ml WL-B indicator. Fourthly, heat the solution under 80~90℃ (boiling). Finally, titrate it using 1.0 mol/L EDTA standard solution and until the solution changes from amaranth to bright yellow. The consumption volume of 1.0 mol/L EDTA standard solution is the EDTA value (pt).

2. Supplement: Add 5.3KG MC-FM7010 into solution while the EDTA value decreases by 1.0 pt. And add 95 ml additve-001, while the pH increase by 0.1 pt.

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