Liquid, multifunctional, phosphoric acid and highly concentrated combination product for concurrent degreasing and phosphating. Used in spraying processes, in single and multi-chamber systems and in high-pressure equipment.
RHOBA SUPRA V103 is a liquid, multifunctional combination product for simultaneous degreasing and phosphating and is used in the spraying process, in single and multi-chamber systems, as well as in high pressure devices.
| 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 particularly heavy soiling, degreasing can be intensified with RHOBA SUPRA Z404. The addition is 0.05 - 0.5 %. After cleaning/phosphatising, rinse the treated components with water. When using a high-pressure cleaner in the circulation process, we recommend a bath concentration of 3% and at least 60°C.
The bath concentration and pH value should be monitored regularly. If a defoamer is required, 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 100 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 0,52
| Appearance | clear liquid |
| Color | colorless to slightly brownish |
| Density at 20 °C | approx. 1,17 g/ml |
| ph-value at 20 °C | 3,5 |
