VOGEL PLEX M203 mineral metalworking fluid is intended for metalworking. It is used as an aqueous emulsion in large centralized systems and machines with individual fluid supply. It significantly improves equipment productivity and the cleanliness of the machined surface.
Key benefits
- Specially developed for machining alloy steels and operations involving high impact loads.
- High resistance to bacterial contamination.
- Effective extreme-pressure additives greatly reduce wear and significantly extend cutting-tool life.
- High cleaning performance.
Composition
Mineral oil, a high-performance VGL-series additive package and biocidal additives.
Safety precautions and storage
Not classified as a hazardous product. In case of contact with skin or eyes, rinse with water. Keep out of reach of children in the manufacturer's tightly sealed container. Protect from sunlight and precipitation.

Application
VOGEL PLEX M203 is intended for use as a process fluid in the form of 2-10% aqueous emulsions for cutting and abrasive machining of ferrous metals, non-ferrous metals, aluminum alloys and copper alloys. It is effective in both individual machines and centralized metalworking-fluid supply systems.
Instructions for preparing the working emulsion
Water and concentrate: use utility-grade water with a recommended hardness of 2-4 °dH. High hardness impairs emulsion properties. The water and concentrate should be at 20-30 °C.
Concentration: the optimal concentration of the finished emulsion is 2-10% by mass, depending on the severity of the operation. Example: to prepare 100 l of a 5% emulsion, use 95 l of water and 5 kg of concentrate.
Important: always add the concentrate to the water while stirring continuously. Do not add water to the concentrate. Use a clean container such as a bucket, drum or system tank.
Mixing: for small volumes, mix manually with a rod. For large volumes, use a mechanical agitator, mixer or compressed air. Mix until a homogeneous emulsion is obtained.
Shelf life: 1 year from the date of manufacture.
