Mobilcut 240
Mobil industrial , Switzerland
Aqueous Metal Working Fluid with innovative technology
Product Description
Mobilcut 240 is a premium quality semi synthetic water miscible metalworking fluid. It is based on innovative technology that offers some outstanding advantages including hard water compatibility, machine tool cleanliness and long term stability. Mobilcut 240 is free from added boron and boric acid, hence meeting the latest Health and Safety related trends.
Mobilcut 240 is formulated using high quality mineral oils and a carefully selected blend of emulsifiers. When mixed with water of hardness 60 °dH or less, the concentrate produces stable, translucent emulsions.
Having a relatively low oil content, Mobilcut 240 provides excellent wetting and detergency and superb cooling and cutting properties, making it suitable for light to moderate duty cutting and grinding applications. It also offers low foam potential and long-term corrosion protection for machine and components. It also helps support machine shop productivity by requiring low maintenance and providing a long term stability.
