BIO-CIRCLE
Back To ProductsProfessional liquid highly concentrated cleaners and degreasers for mechanical parts washing and degreasing. Can be applied as pre- and intermediate cleaners in the metalworking and metal processing industry and as VOC substitutes.
- Low-foaming
- Optimal cleaning temperature at 60 °C.
- Demulsifying - oil and grease input can be removed by means of mechanical methods (e.g. plate separator).
- Very low application concentration (from 0.5%).
Field of use
Universal - can be applicaed manually and mechanically (e.g. in pressure washers and ultrasound cleaning devices).

| Cleans aluminium, non-ferrous metals, galvanized metals, high gloss polished brass without pitting the material. Silicate- and salt-free. Developed for simple cleaning and degreasing jobs. | Alkaline fine-tuned for the cleaning of steel, iron, casting and plastics. High dissolving power for oil and oil residues, grease-and soot residues. | Highly alkaline cleaner for the removal of most persistent pollution such as oil incrustations, resin formations, anti-friction- and roller bearings, wheel sets or single varnish layers. | ||

Defoamer to be used in hot-water parts washers and wherever foam would have a disruptive effect. Specifically developed for the aqueous bio-chem cleaning agents.
- Fast and permanent foam destruction
- Good dispersability and easy spreading
- Very economical - low application concentration
| Defoamer with silicone |
Defoamer silicone-free |

Low-foaming corrosion inhibitor for the neutral and alkaline bio-chem cleaning agents, the bio-chem welding protection sprays, and for passivation baths and water treatment media. Contains 100% active ingredients and provides temporary corrosion protectioni for steel-iron- and casting materials.
- Free from mineral oil, nitrite, PTBB, and from secondary amines and phosphor compounds
- Very economical - low application concentration
- Also suited for application in BIO-CIRCLE parts washers
Fields of use
Particularly suited to substitute nitrite-containing anti-corrosion formulations in neutral and alkaline solutions.
| Corrosion protection for aqueous systems Degree of corrosion = 4 |

Grey iron shavings test in accordance with DIN 51 360 Part 2:
Grey iron shavings are placed on a white filter and wetted with the liquid to be examined. After 2 hours the shaving are removed, and the corrosion deposits on the filter are evaluated.

Without corrosion protection:
Degree of corrosion = 4

With 2.5% corrosionprotection
for aqueous systems:
Degree of corrosion = 0
