T.C. 679

DESCRIPTION

T.C. 679 is a 100% synthetic tube forming a coolant formulated for use on ferrous and most non-ferrous metals. It has excellent hard water stability and does not produce gummy or sticky residues that can interfere with roll forming or welding operations. T.C. 679, when mixed with water, is formulated to be non-foaming and is resistant to the development of bacterial and fungal odors and growths that often clog filters, strainers and coolant supply lines. This product is effective in providing long roll life and excellent part finish. It is important in maintaining a competitive edge in today's economy. Solutions of T.C. 679 provide maximum corrosion protection of finished tubing parts, are environmentally "clean," will resist outside contaminates, and will encourage good worker acceptance.

APPLICATION

T.C. 679 is designed for use at 7% concentration or one part coolant concentrate to 14 parts water for best results and maximum rust protection. This product is also capable of doing matching at 5% starting concentration and grinding operations with a starting strength of 2% to 5%. For greatest longevity, machines and equipment should be cleaned with Tru-Chem Machine Cleaner before initial charge and subsequent recharging. When systems are used infrequently or allowed to stand idle for extended periods, a good biocide is recommended to prevent spoilage.
