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.
RHOBA SUPRA V102 is a liquid combination product for simultaneous degreasing and phosphating and can be used by spraying, in single and multi-chamber systems, and by means of 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 amounts to 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.
10ml of the cleaning bath to be tested is added to a 250ml Erlenmeyer flask using a pipette. Add 50 ml of deionized water and 5 drops of the indicator solution (phenolphthalein solution, 1%). With 0.1M sodium hydroxide solution (NaOH), tritrate until the color changes from colorless to pink or red.
Calculation of concentration:
Concentration (Vol.%) = [consumption 0.1M sodium hydroxide solution (NaOH in ml)] x 0.31
Appearence | clear, brownish |
Density at 20 °C | approx. 1,22 g/ml |
ph value at 20 °C | 2 - 3 |
