Henkel Bactericide-free metal-cutting fluid solves biological contamination problems
With its new-generation Multan-brand bactericide-free metal-cutting fluids, already proven in industrial practice, Henkel AG eliminates key drawbacks of water-miscible metalworking fluids, namely, the splitting of emulsions when in use and the bad odour that follows. The source of the problem is bacterial contamination that naturally takes place when machines are idle for too long. Multan 71-2 products provide a solution that is superior to traditional approaches.
Even advanced-technology machining centres are susceptible to bacterial growth, emulsion splitting and, ultimately, odour buildup. The problems of unwanted microorganisms and emulsion splitting have traditionally been tackled by using metal-cutting fluids containing bactericides or by adding bactericides to bactericide-free fluids once bacterial growth reaches an intolerable level. However, exposure to either bacteria or bactericide poses a potential health hazard for employees. And frequently changing emulsions that have split and become unusable is both costly and a burden on the environment.
The patented emulsifier technology of Henkel’s Multan 71-2 offers a sustainable alternative. The microbiologically robust cutting fluid is formulated without any bactericides such as formaldehyde splitters, and it does not require the later addition of bactericides to remain stable. The new product is suitable for many different kinds of machining, from roughing to grinding.
