Chlorine-Free, Semi-Synthetic Coolant

Ultra-high lubricity for machining aerospace and medical device alloys

Chemetall’s Tech Cool 35052CF is a new, high-performance semi-synthetic metalworking coolant that combines “ultra-high” lubricity characteristics required for aerospace and medical device alloys with green chemistry technologies. The result is exceptional emulsion stability, outstanding sump life without odors, extended tool life, low foam levels, excellent corrosion resistance, and significantly lower operational costs, according to the developer. All this is achieved without chlorinated or sulfur-based EP additives, and without bactericides, DCHA, or secondary amines, Chemetall said, adding that Tech Cool 35052CF is free of formaldehyde-releasing compounds.

Chematall is a specialty chemical company that develops products for metalworking, drawing and stamping compounds, rust preventatives, and surface treatment. “Tech Cool 35052CF complements our family of high-performance semi-synthetic coolants,” according to v.p. - technical marketing Julia Murray. “We now have a chlorine-free offering suitable for the most challenging substrates to complement our original Tech Cool 35052 chemistry.”

The developer explained that the strength of it Tech Cool series is the stability of its micro-emulsion technology. The ability to reject tramp oils supports effective coolant recycling programs, generates drier chips that are easier to separate, and reduces residues on the parts and the tooling.

It noted that Tech Cool 35052CF is very low foaming, without the use of silicone defoamers, and is suitable for high-pressure, high-speed systems, even in low hardness water. It is stable in 1,200 ppm water hardness, and represents a versatile product of choice when performance and economics is required.

The developer recommends the new formulation for titanium, high-nickel alloys, and stainless steels, and noted that it is compatible with aluminum, brass and all ferrous substrates. It called Tech Cool 35052CF “the ideal solution” for metal removal, and “the ideal product” for grinding, broaching, milling, or drilling, for central systems and standalone machines.
