Master Chemical semi-synthetic cutting fluid is low foaming and cust costs

These latest coolants were developed in the UK for the European market at the request of customers. Their unique formulation ensures low levels of foam that are not generally seen with other fluids of their type, especially in soft water areas, while the are also extremely hard water tolerant. The products are said to be versatile, able to work well in a wide range of operations, such as grinding, milling, turning, drilling and tapping. TRIM SC617 additionally contains a traditional extreme pressure (EP) additive that boosts cutting performance for difficult-to-machine materials. For example, it is highly effective in turning stainless steel and other hard steels. Low consumption is another main benefit of TRIM SC415 and SC617. Typically, instead of topping up with a 1-2 per cent dilution to achieve a 5 per cent concentration, 0.5 per cent of the new semi- synthetics is required. Indeed, when trialled in a 50,000 litre central system, consumption of TRIM SC415, by comparison with the previous semi-synthetic, dropped by an impressive 50 per cent. A similar example was confirmed by a company grinding rotors at high pressure and with soft water. This combination of factors meant there was a constant need for additions of anti-foam, but TRIM SC415 demonstrated it did not require this costly additive.
