Contram OF - G (Bakterizid)
Item number: 1931 01
CONTRAM™ OF-G is a liquid antimicrobial agent primarily used to treat bacterial growth in tanks.
Since CONTRAM™ OF-G contains no nitrogen, it does not contribute to nitrosamine formation.
The recommended application rate for metalworking fluids is 0.1–0.2% in the final dilution. Efficacy, stability, and compatibility should be verified in a laboratory before use.
CONTRAM™ OF-G is an effective, fast-acting bactericide that is free of heavy metals, phenols, halogens and complexing agents.
CONTRAM™ OF-G has a neutral pH and can therefore be easily incorporated into preparations such as:
- Water-miscible coolants
- Dye dispersions
- Other aqueous systems
CONTRAM™ OF-G is not compatible with acids or oxidizing agents.
