Rhenus Lub has developed a high-performance fluid without labelling requirements that also omits formaldehyde depots
Lubricant manufacturer Rhenus Lub has developed the fluid FU 800, which it says contain no amines, boric acid or formaldehyde depots. The new product therefore already meets the strictest health and safety requirements and there is no need for labelling.
“Even at the development stage, we have consistently avoided the use of ingredients that are currently the subject of intense debate”, says Dr. Hans-Jürgen Schlindwein, Head of Coolant Research & Development at Rhenus Lub. He believes that rhenus FU 800 is a prime example of a modern coolant that combines all the positive characteristics and is fit for the future of machining. In detail, this means that the lubricant specialists at Rhenus Lub are consistently avoiding not only amine and boric-acid-based additives and also a formaldehyde depot. In addition, a new emulsifier system has also been developed especially for rhenus FU 800, which foams less and has good flushing properties.
The consistent selection of ingredients means that there are no labelling requirements for rhenus FU 800. This is a distinct advantage for users in the metalworking industry, since from June 1, 2015, preparations, including coolants, have to be categorised under the GHS/CLP Regulation (Globally Harmonised System, Regulation on Classification, Labelling and Packaging of Substances and Mixtures).
According to Rhenus Lub, many users still believe that for a coolant to perform well, it must have added amines and boric acid. rhenus FU 800 lays this misconception to rest. In a range of practical tests, even before its market launch, the innovative coolant has proven that it performs at least as well as amine and boric-acid-based fluids.
Testing has also demonstrated that the fluid can be universally used in demanding machining applications, for example in the aviation industry, where many workpieces have to be milled from a single solid piece of material, ranging from grey cast iron to aluminium through to titanium. According to the company, in extensive testing conducted at 14 customers on 18 machines, the new coolant has yet to reach its performance limits.
