Boron-free coolant has pedigree

Master Chemical’s TRIM C272 is a boron-free development of its C270 formulation.

A high performance synthetic cutting and grinding fluid, C270 has become the preferred choice of many manufacturers worldwide. It has Rolls-Royce CSS130 approval, for example. In several EU countries the use of boron and formaldehyde donor biocides as constituents in metalworking fluids are heavily restricted. While TRIM C272 retains all the performance qualities of TRIM C270, it does so without the inclusion of boron and formaldehyde donor biocides. As a result, it can be used anywhere throughout the EU or, indeed, the world, allowing global companies to standardise on the product without fear of infringing ‘local’ environmental legislation. This new addition inherits all the characteristics of TRIM C270. It provides excellent cooling, chip settling, good tramp oil rejection and filterability and meets the needs of the modern machine shop. It is particularly suited to applications where high coolant volumes and velocities are prerequisites of achieving maximum productivity. TRIM C272 is compatible with a very wide range of materials including cast iron, mild steels, corrosion resistant steels as well as plastics and composites. It utilises a proprietary chlorine and sulphur-free extreme pressure additive that effectively controls built-up edge and ensures good tool life and surface finish. Another characteristic that TRIM C272 carries forward to the next generation is clean running machines and parts protection. It leaves a protective fluid coating that is resoluble in coolant working solution and minimises the build-up of sticky residues that can harbour abrasive chips. It is also ideal for recycling.
