13/10/10 – Cutting Fluids that inhibit bacterial growth
13 October 2010
Henkel Ltd has launched two cutting fluids described as easy to use, has developed water-miscible and bactericide-free. The company says that the cutting fluids reduce health risks to employees, and implement prospective EU Biocides Regulations. Multan 71-2 and 77-4 incorporate a new technology that prevents bacteria from absorbing nutrients from the degradation of emulsifiers. This normally occurs once a certain minimum bacteria concentration has been reached.
The general purpose Multan 71-2 is multifunctional, and because of its high lubricity is suitable for all types of machining, including grinding. For high-alloy steel and aluminium machining, special purpose Multan 77-4 provides extremely high lubricity even at low concentration. This product is especially suitable for centreless grinding.
Neither product contains formaldehyde releasing agents and both are odourless. Also, because the finely dispersed emulsion runs off the machined parts quickly, they both have a low drag-out rate.
‘Unlike previous technologies, the formula of the new products avoids hazardous bacterial growth which usually occurs during the use of cutting fluids,’ reports Colin Chapman, Marketing Manager at Henkel. ‘Just as important, this is accomplished without any toxic bactericidal additives and without sacrificing the quality and performance of the products.’
