Minimal foam from Master Chemicals

Foam can compromise production, even stopping it, so most products require a conventional defoamer, but this is an added expense, another procedure and its use can also result in filter blockages. TRIM VHP E820 has been formulated to meet the requirements of EU manufacturers and contains no chlorine, sulphur, boron or formaldehyde donors. TRIM VHP E820 is particularly suited to the production of aerospace parts, a benefit that is confirmed by Pratt and Whitney approval. TRIM VHP E820 is suited for operations that use high-pressure, high-volume coolant. It improves the benefits of through-the-tool coolant delivery systems on vertical and horizontal machining centres, and will help achieve the good productivity from creep feed and VIPER grinders. This clean emulsion reduces carry-off for low total operating cost and permits fast wetting for excellent lubrication and superior corrosion protection of the workpiece. Compatible with all metals and many non-metallic materials too, 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 friction and reduction and control of built-up edge are critical.
