KOOLRite™ 2365 Semi-Synthetic Cutting Fluid

Semi-Synthetic Cutting Fluid for Heavy Duty/Severe Machining

KOOLRite 2365 is a proven, new generation semi-synthetic, chemical emulsion that uses advanced cutting fluid technology to provide a new level of machining performance. KOOLRite 2365 outperforms heavy duty chlorinated soluble oils, semi- synthetics, and newer polymer-based synthetic coolants with a machining performance not seen in any competitive coolant.

KOOLRite 2365 is designed for heavy duty/severe machining operations on all metals with excellent performance on tough aerospace alloys where high finish important. It has proven performance on metals with less than 15% machinability and high nickel alloys.

KOOLRite 2365 is formulated with JTM’s unique BioArmor Technology which gives outstanding control of bacteria without the use of bactericides. BioArmor stops sump odors, gives you exceptionally long sump life and a clean, comfortable, safe work environment for machine operators.

KOOLRite 2365 will reject tramp oils, allowing clean coolant to be delivered to the chip/tool interface keeping your machine tool clean with a minimum of residual film, while providing excellent corrosion control.

Directions for Use

The sump life of this coolant, as with any other coolant will be greatly enhanced if charged to a clean system. You can utilize JTM's Sump Cleaner to disinfect your sump. KOOLRite 2365 can be metered through automatic dispensing systems available from JTM. Contact your representative regarding cleaning procedures and dispensers. Always add the KOOLRite 2365 concentrate to the water and not the water to the concentrate. Proper maintenance by removing tramp oils is beneficial for extended coolant life. The concentration can be monitored by refractive index.

Refractive Index …………1.71
(Refractive reading x 1.71 = % of concentration of dilution)
