Setting up of passivation solution
- Warm up 100ml-bottle of Antitarnish-A-100 to 45-50°C.
- Warm up 9.9 liters of deionised water to 45-50°C in a tank (i.e. polypropylene).
- Shake thoroughly warmed up bottle of Antitarnish-A-100 concentrate and pour out passivation concentrate in the tank of 9.9 liters deionised water.
- Stir this solution for 5 min and keep solution temperature at 45-50°C (optimum: 50°C).
- Put 25-50 grams of A-100 PRO-SALT (conducting salt) into solution and dissolve by stirring.
- Adjust the pH-value of the passivation bath with sodium hydroxide to pH 3.7.
- The passivation bath Antitarnish-A-100 PRO-KIT is now ready for use.
Passivation process
- Use mixed metal oxide coated titanium anode and apply a voltage of 3.5-5.0 V to the passivation bath.
- Dip workpieces into softly agitated passivation bath at 45-50°C.
- Take out workpieces after 5-7 min.
- Firstly rinse in cold (= room temperature) deionised water for 10-20 sec.
- Then rinse in 50-60°C warm deionised water for 1 min.
- Dry workpieces with hot air (max 60°C) or put workpieces in oven (max. 60°C).
- Now the workpieces are passivated and protected against tarnishing and oxidation processes.
