FIGHTING BACTERIA WITH PRECIOUS METAL:

The Green Revolution

MOTOREX TRESOR PMC®
Water-miscible cooling lubricants are a crucially important element of demanding metal machining processes. In nature, life cannot exist without water – but the water, mineral oil and emulsifiers used in machine tools can turn them into ideal incubators for bacteria and fungi. Up to now, chemicals such as boron, amines, fungicides or bactericides have had to be regularly used to check this persistent growth. The need for such “chemical bludgeons” is now over! MOTOREX presents a world first: SWISSCOOL TRESOR PMC® (Precious Metal Catalyst) – the first cooling lubricant concentrate that impedes and sustainably limits bacterial growth using bioactive precious metals instead of biocides.


Drilling, milling, turning and grinding – machining operations that send swarf flying everywhere call for heavy-duty cooling and lubrication. Cooling  lubricant is flooded over the tool and workpiece. Water mixed with finely dispersed droplets of oil forms an emulsion that effectively cools and reduces friction. These emulsions also contain additives that ensure optimum cutting performance and high-quality surface finishes. Ingress of foulants carried by raw materials, leakage oil and other impurities promotes the growth of microorganisms in the emulsion circuit. This results in noxious odors, corrosion, sediment and deposits, etc., that necessitate changing the coolant fluid. Up until now, the only truly effective means of countering such coolant degradation were stabilizers such as fungicides and bactericides which, however, pose hazards for humans and the environment. This is why the use of such problematic substances has become the subject of broad debate worldwide and faces growing, justifiable challenges from the workplace in particular.                                                                                                                   
 		  
Many areas of science and technology, including human medicine, use the antibacterial effect of precious metals: with TRESOR PMC®, MOTOREX has succeeded in integrating this technology into an innovative cooling lubricant with long-term action.
