• thoroughly cleans light metals and ferrous materials
• can be added via a pH-value-controlled liquid metering pump
• ideal as a temporary corrosion protection and adhesion base for the following painting processes

The product is a liquid combination product for simultaneous degreasing and phosphating and is used in spraying processes, in single- and multi-chamber systems, as well as in high-pressure equipment.

For optimum results, the pH value must be adjusted to 4.5 - 4.8 by adding RHOBA SUPRA Z401. The pH-value should be checked regularly. In case of particularly heavy soiling, degreasing can be intensified with RHOBA SUPRA Z404. The addition values 0.05 - 0.5 %. After cleaning/phosphating, rinse the treated components with water.

When using a high-pressure cleaner in a circulation process, we recommend a bath addition of 3% and at least 60°C.
If a defoamer is necessary, we recommend RHOBA PURIA S103 or RHOBA PURIA S104.

Add 10ml of the cleaning bath to be tested into a 250ml Erlenmeyer flask by means of a pipette. Add 50ml deionised water and 5 drops of the indicator solution (phenolphthalein solution,1%). Add 0.1M sodium hydroxide solution (NaOH) and tritrate until the colour changes from colourless to pink or red.

Calculation of the concentration:
Concentration (vol.%) = [consumption 0.1M sodium hydroxide solution (NaOH in ml] x 0.41

Check material compatibility in an inconspicuous place before use. Follow the manufacturer's cleaning and care instructions!
