Two new cutting fluids

This reduces the need to add expensive treatment additives and biocides, as well as safeguarding against costly uncontrolled system changes.

Castrol’s Hysol and Alusol XBB products do not rely on the use of boron or formaldehyde releasing agents or additional biocide and fungicide additive packs, yet are still able to meet and exceed the lifetime expectations of the benchmark technology to date. In many cases, customers have been able to significantly reduce or completely eliminate the use of biocides from their management processes.
 
Castrol says the cutting fluids are resistant to acid attack from bacteria, proven to maintain pH at a constant level and are therefore inherently more resistant to bacterial growth.
 
Dr Rudi Janner, Castrol Global Product Manager for Cutting Fluids said: “Our liquid engineers have reinvented the fundamentals of cutting fluid technology. By having greater control of the pH, the reliance upon short-lived biocides to control bacteria is significantly reduced or eliminated. This ultimately translates into significant improvements for controlling manufacturing costs, increasing productivity, protecting the quality of end products and meeting HSSE requirements.”

Castrol Hysol SL 35 XBB is for use with ferrous alloys while Castrol Alusol SL 51 XBB helps improves precision performance in aluminium machining.

By maintaining system stability, the unpleasant odours produced by an emulsion that is suffering from a large population of bacteria are minimised and the reduced need for testing pH levels reduces potential skin complaints for workers. Furthermore, the reduced need for biocide additives minimises the need for workers to handle dangerous chemicals.
