Bonderite L-MR 21972


Bonderite L-MR 21972 is mainly used for the machining of aluminium, steel and cast iron. An inhibitor avoids the discoloration of high-silicon containing aluminium alloys. If you need to create / mix emulsions in exact concentrations we recommend the use of a dosing pump.


Bonderite L-MR 21972 is a low-foam mineral oil-based general purpose coolant suitable for a wide range of operations especially in soft water areas (0-30 °GH)
