Years ago, Chemetall innovated a complete line of semi-synthetic Tech Cool metalworking fluids with no formaldehyde-releasing biocides. Recently, the U.S. Department of Health and Human Services' National Toxicology Program (NTP) formally classified formaldehyde as a known human carcinogen. The NTP specifically identified triazine, widely used in conventional metalworking fluids for microbial control, as a formaldehyde-releasing compound. Chemetall's Line of Tech Cool products: 35052, 35052M, 35048, and 35200 are manufactured without the use of the triazine, other formaldehyde releasing biocides, or DCHA.
To inhibit bacterial growth, Chemetall employs only the highest grade raw materials, proven sanitary maintenance practices and fluid control, and advanced microemulsion technologies in the production of the Tech Cool line. Tech Cool exhibits high lubricity, enhanced corrosion control, and increased tramp oil rejection, even in high pressure applications. Not only is Tech Cool compatible with ferrous and aluminum alloys, it also can be utilized in stand-alone machine sumps and central coolant systems. Because these semi-synthetics are stable in hard water, low foaming and residue-free Tech Cool is also ideal for recycling operations.
"We at Chemetall are committed to engineering metalworking fluids of the finest quality and superior performance," said Julia Murray, Vice-President of Technical Marketing. "With the NTP's announcement of formaldehyde as a known cancer-causing agent, we are pleased to have had formaldehyde-releasing bactericide-free Tech Cool already available. The welfare and success of our customers is our utmost concern. Tech Cool is good for our customers' health, processes, environment, and their bottom line."
Related Glossary Terms
- alloys
alloys
Substances having metallic properties and being composed of two or more chemical elements of which at least one is a metal.
- aluminum alloys
aluminum alloys
Aluminum containing specified quantities of alloying elements added to obtain the necessary mechanical and physical properties. Aluminum alloys are divided into two categories: wrought compositions and casting compositions. Some compositions may contain up to 10 alloying elements, but only one or two are the main alloying elements, such as copper, manganese, silicon, magnesium, zinc or tin.
- coolant
coolant
Fluid that reduces temperature buildup at the tool/workpiece interface during machining. Normally takes the form of a liquid such as soluble or chemical mixtures (semisynthetic, synthetic) but can be pressurized air or other gas. Because of water’s ability to absorb great quantities of heat, it is widely used as a coolant and vehicle for various cutting compounds, with the water-to-compound ratio varying with the machining task. See cutting fluid; semisynthetic cutting fluid; soluble-oil cutting fluid; synthetic cutting fluid.
- lubricity
lubricity
Measure of the relative efficiency with which a cutting fluid or lubricant reduces friction between surfaces.
- metalworking
metalworking
Any manufacturing process in which metal is processed or machined such that the workpiece is given a new shape. Broadly defined, the term includes processes such as design and layout, heat-treating, material handling and inspection.
- tramp oil
tramp oil
Oil that is present in a metalworking fluid mix that is not from the product concentrate. The usual sources are machine tool lubrication system leaks.
