RHOBA SUPRA V102
Old productname: RHOBASUR S 105 EPMultifunctional degreasing, rust removal and phosphating concentrate. Used in spraying processes, in single and multi-chamber systems and in high-pressure equipment.
Multifunctional degreasing, rust removal and phosphating concentrate. Used in spraying processes, in single and multi-chamber systems and in high-pressure equipment.
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.
Application | Concentration | Temperature | Processing time | Spray pressure |
Spraying | 1,5 - 3,0 wt.% | 55 - 60 °C | 1 - 3 min | 1,0 - 2,0 bar |
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
Appearence | clear, brownish |
Density at 20 °C | approx. 1,22 g/ml |
ph value at 20 °C | 2 - 3 |
