Synkool SS™ is a concentrated water-soluble, semi-synthetic, biostable, low foaming, non-staining metalworking fluid for use in grinding and other high-speed light to heavy-duty machining operations on both ferrous and non-ferrous metals. It’s especially recommended for use in metalworking fluid operations that employ the use of high-pressure machines.

Synkool SS™ possesses excellent cooling, extreme pressure and lubricity properties needed for high speed machining operations. Synkool SS™ contains surface-active ingredients, which enable the fluid to wet and lubricate the metal surfaces of the tool and the workpiece. Synkool SS™ also contains synthetic lubricity and anti-weld additives that provide extreme pressure protection to reduce the coefficient of friction and heat between the tool and the workpiece interface. This in turn results in greater dimensional accuracy, higher turning speeds and feeds, prevention of the chips from welding to the cutting tools, improved surface finish and extended tool life.

• Excellent cooling and lubricity.
• Eliminates smoking and misting characteristics.
• Provides strong detergency action to keep machine and tools clean.
• Resists rancidity and drop in pH, which prevents rusting.
• Excellent bioresistance and biostability.

#311 SYNKOOL SS™ DESCRIPTION: Synkool SS™ is a concentrated water-soluble semi-synthetic, biostable, low foaming nonstaining metalworking fluid that is recommended for use in grinding and other high speed light to heavy duty machining operations on both ferrous and non-ferrous metals. Synkool SS™ does not contain any active sulfur, chlorine, nitrites, phenols, Diethanolamine (DEA) or heavy metals. Synkool SS™ is especially recommended for use in metalworking fluid operations that employ the use of high-pressure machines.

EXCELLENT COOLING AND LUBRICITY: Synkool SS™ possesses excellent cooling, extreme pressure, and lubricity properties that are needed for high speed machining operations. Synkool SS™ contains surface-active ingredients, which enable the fluid to wet the metal surfaces of the tool and the workpiece in order to provide a protective film for lubricating the tool and the workpiece interface. Synkool SS™ also contains synthetic lubricity and anti-weld additives that function as extreme pressure agents that reduce the coefficient of friction between the tool and the workpiece interface. This combination of cooling and extreme pressure/lubricity properties effectively transfers heat away from the cutting zone, thus reducing friction between the cutting tool and the workpiece. This in turn results in greater dimensional accuracy, higher turning speeds and feeds, prevention of the chips from welding to the cutting tools, improved surface finish and extended tool life.

ADDITIONAL PERFORMANCE FEATURES: Synkool SS™ contains an effective low-foaming emulsifier system that allows the Synkool SS™ to be mixed with water at varying concentrations. This emulsifier system allows the oil portion of the Synkool SS™ to be evenly and uniformly dispersed throughout the coolant mixture. This even and uniform dispersion results in a transparent emulsion that allows the operator the ability to see the workpiece being machined. Further, by being evenly and uniformly dispersed, the smoking and misting characteristics that are associated with the use of soluble cutting fluids is virtually eliminated. This emulsifier system also provides a detergent action that allows the Synkool SS™ the ability to break up and dislodge dirt and grit in order to keep the machine and tools clean. This detergent action also assists in flushing of the chips and fines away from the cutting area.

• Allows for better visibility of the workplace.
• Able to machine at high speeds and feed rates.
• Protects against rancidity and Monday morning smell.
• Superior rust and corrosion inhibition on all ferrous and nonferrous metals.

The emulsifier system further complements and enhances the performance characteristics of Synkool SS’s rust and corrosion inhibiting additive package. The emulsifier system enhances the rust and corrosion inhibitors’ alkaline reserve during use resulting in the Synkool SS™ being able to resist rancidity, a drop in pH and prevention of the rusting of parts, tools, and machinery. Synkool SS’s emulsifier system contains sequestering agents which combat iron, calcium and magnesium ions in hard water up to 400 ppm; thus preventing the formation of hard water soaps, scum, and resins on the machine and the parts.

EXCELLENT BIORESISTANCE and BIOSTABILITY: Synkool SS™ contains an effective broad-spectrum anti-microbial agent that allows the Synkool SS™ to resist bacterial and fungal growth during use. This broad-spectrum anti-microbial agent unlike conventional biocides found in conventional soluble cutting fluids is not readily used up during usage. This means that Synkool SS™ is less likely to sour and produce odors resulting in longer sump life and less worker complaints. Synkool SS™ will reject a very high percentage of tramp oil contamination allowing for easy skimming and removal of the tramp oils from the sumps and reservoirs. This results the elimination of a potential food source for the growth of bacterial and fungus in the sump and greater bioresistance to the growth of bacteria and fungus in the coolant sump. In addition Synkool SS’s emulsifier system possesses less susceptibility to attack from bacterial growth. This results is less degradation of the fluid during use. All of these factors result in a very biostable coolant that is able to resist extreme biological degradation. This results in long sump life in a properly maintained machine tool and diminishes the possibility of “Monday Morning Odor”.

VERY LOW FOAMING CHARACTERISTICS: Excessive foaming of a cutting fluid especially when used in high pressure machining operations during use can result in an insufficient amount of the cutting fluid being available at the tool-workpiece interface and in maintenance problems due to metalworking fluid overflow in sumps. Synkool SS™ contains a highly effective non-silicone base antifoam additive system that allows the product to exhibit very low foaming characteristics. The non-silicone base antifoam additive system provides rapid defoaming and a high degree of stability during use. This results in a sufficient amount of the cutting fluid being available to the tool-workpiece interface, greater visibility of the workpiece and a vast reduction in maintenance problems due to coolant overflow. In addition the antifoam additive will not result in any deposition of residues on the workpiece. This results in less cleaning of the metal parts and ease of painting or further processing of the part after machining.

WASTETREATABILITY: Synkool SS™ is a water waste treatable product that can be safely discharged into the normal flow of the wastewater from the plant. The only time Synkool SS™ cannot be discharged into a wastewater system is if the wastewater treatment facility is not a primary wastewater treatment facility. Before being discharged into the wastewater system, all tramp oils and metal fines should be removed from the Synkool SS™. In some areas, it is necessary to remove all traces of alkalinity before dumping watery wastes. For these areas it is suggested the following procedure be followed: Skim all tramp oils and remove all metal fines. To the remaining clarified water, neutralize to a pH of 7.0 by the use of muriatic acid. Approximately 2 quarts of muriatic acid should be enough to neutralize 100 gallons of a used 20:1 mixture of Synkool SS™. Add a small amount of acid at a time and check the progress using a pH indicator paper or a pH meter. When a pH of 7 is reached, the spent Synkool SS is ready to be discharged into the plant waste effluent.
