Biocides for Metalworking Fluids

Biocides are used in water-miscible metalworking fluids to control bacteria, yeasts and moulds. A properly selected preservation system helps maintain the microbiological stability of the concentrate and working emulsion within the limits required by the formulation and operating conditions.

The active substance is selected according to the fluid composition, working pH, temperature, water quality, expected microbiological load and compatibility with emulsifiers and other functional additives. Labelling, handling and finished-fluid safety requirements must also be considered.

Range of Biocides for Metalworking Fluids

The REVADA catalogue includes RevaPro products based on BIT, CMIT, OIT, MBM, HHT and SPT, as well as combined formulations. The available options make it possible to select a preservation system for the specific concentrate and working fluid.

The current composition, recommended application and restrictions for each grade should be checked against its technical data sheet and safety data sheet.

Selecting a Biocide for a Formulation

Before implementation, compatibility with the complete formulation and performance under the intended conditions should be evaluated. REVADA specialists can help identify suitable grades, provide documentation and arrange samples for testing. Treat rates must follow the manufacturer’s recommendations and test results.
