For the past three decades, our wish list as a premier, specialty chemical formulator has remained relatively unchanged. However, at the top of the list was the need for a coolant providing improved aluminum lubricity without sacrificing performance on ferrous metals; true multi-metal capabilities. Of near-equal importance has been the need for a bio-resistant formulation that does not rely on heavy concentrations of biocides and fungicides. Effective tramp oil rejection is necessary in order to maintain consistently high levels of performance in the presence of lubricant contaminants while minimizing smoke and mist. And finally, and perhaps the most elusive, has been the ultimate desire to develop a fully-synthetic coolant with the performance characteristics of soluble oils.

International Chemical Company has introduced the 7900 Series of Machine and Grinding Coolants. International Compound #7950 is a full-synthetic meeting all of the aforementioned criteria. This coolant has been engineered with bio-stable additives that reportedly eliminate the added cost and labor of sump-side biocides, fungicides and defoamers. International Compound #7951 is a semi-synthetic coolant which utilizes the very same platform, but with 7 percent of a hydro-treated, premium naphthenic oil providing enhanced lubricity, particularly in tapping operations and those incorporating specific grades of aluminum.
