Master Chemical Unveils Minimal-Foam Concentrate

Master Chemical Europe has introduced the Trim VHP E820 minimal-foam cutting and grinding fluid concentrate. According to the company, the concentrate does not foam, even at pressures greater than 150bar and when diluted with soft water. This stable product has been formulated specifically to meet the requirements of European Union manufacturers and does not contain any chlorine, sulphur, boron or formaldehyde donors.

Trim VHP E820 is suitable for the production of aerospace parts - a benefit that is confirmed by Pratt and Whitney approval. It is also said to be ideal for operations that use high-pressure, high-volume coolant. It maximises the benefits of through-the-tool coolant delivery systems on vertical and horizontal machining centres and will help achieve the best productivity from creep-feed and Viper grinders, according to Master Chemical.

This clean emulsion reduces carry-off for a low total operating cost and permits fast wetting for lubrication and the corrosion protection of the workpiece. Compatible with all metals and many non-metallic materials, this new coolant can run at lower concentrations for higher-speed operations where heat removal is a key issue. Higher concentrations are recommended on soft materials and for lower-speed operations where the friction, reduction and control of built-up edges are critical.
