Thermal Stability
The Cincinnati Milacron Thermal Stability Test is used to evaluate the thermal stability of fluids in the pres-ence of copper and steel at elevated temperatures for 168 hours. Normally, run at 135°C, KR-015FG and a PAO were tested at elevated temperatures (200°C and 225°C) both neat and with an package containing an antioxidant and a yellow metal deactivator. Not surprisingly, due to breakdown and polymerization, the PAO experienced a very high viscosity increase.

Thermo-Oxidative Stability Both KR-015FG and KR-029FG demon-strated significant performance advantages over PAO (blended to an equal viscosity) when tested in the Rotating Pressure Ves-sel Oxidation Test (RPVOT-ASTM D 2272) as neat fluids and with the addition of 0.2%antioxidants. When tested using Pressure Differential Scanning Calorimetry versus both a white oil and PAO, at 200°C and 210° C, the KR products again demonstrated their superior oxidative stability.

Multi-functional Additive NA-LUBE® AW-6400FG NA-LUBE AW-6400FG is an ashless, HX-1 approved, multi-functional additive that offers anticorrosion, antiwear and EP properties. It is especially well suited for food grade lubri-cants that require rust protection and high load capacity (FZG) at low treat levels. Typically used in the 0.10 - 0.50% range, NA-LUBE AW-6400FG is: • Light in color • An easy to handle, liquid • Soluble in all common food grade basestocks and most
common solvents

Antioxidant NA-LUBE® AO-142 NA-LUBE AO-142 is a butylated, octylated, diphenylamine antioxidant that can be used at levels up to 0.50% in food grade applications. It is ashless, non-corrosive and soluble in a wide range of H-1 base fluids. As shown in the test data that follows, additive levels of 0.2% and 0.5% NA-LUBE AO-142 in various base oils resulted in a significant increase in the lifetime as measured by RPVOT - ASTM D 2272. NA-LUBE AO-142 is a liquid product for easy incorporation and imparts enhanced thermal and oxidative stability.

Yellow Metal Deactivator/Corrosion Inhibitor K-CORR® NF-200 K-CORR NF-200 is a HX-1 food grade approved yellow metal deactivator that protects copper and copper alloys against corrosion initiated by active sulfur. K-CORR NF-200 also enhances the oxidation stability of food grade lubricants and greases when used in combination with HX-1 food grade approved NA-LUBE® AO-142 and an ashless dithiocarbamate. K-CORR NF-200 is recommended for formulating high perform-ance food grade circulating and steam turbine oils, hydraulic oils, vacuum oils, and industrial gear oils, as well as greases.
