New coolant for pH values 7.5 to 8.5 is kind to environment

A new generation of amino- and bori-acid-free cooling lubricants r.meta R-SEVEN can be safely used where pH value fluctuates between 7.5 and 8.5, yet features no additives. In the development of the new generation, scientists at Rhenus Lub’s laboratory centre forewent the addition of bactericides, plus, for ecological reasons, all color additives were removed from the formula. The low pH value used to formulate the emulsion, which is under 8, ensures excellent coetaneous tolerance. This value slows down micro-organism growth considerably and the impact of foreign substances, such as hydraulic oil residues, metal oil residue, cleaners or other cooling lubricants is not as grave. While these cooling lubricants deliver even better pH neutrality, they also exhibit improved processing stability. Moreover, the new cooling lubricant generation demonstrates improved dispersion and increased flushing capabilities. * In cases where the pH value rises above 8.5 due to external processing influences, users should contact the experts at Rhenus Lub who will help them determine and eliminate the cause.
