Bio-Ultimax? 1200LT (Low Temperature) Hydraulic Fluids are ultimately biodegradable1, biosynthetic formulas that were designed specifically to replace mineral oil based hydraulic fluids for environmentally sensitive and/or cold temperature areas. These patented biobased hydraulic fluids are formulated to perform in high and low pressure hydraulic systems that require Anti-Wear (AW), anti-rust, anti-oxidation, anti-foam, and demulsibility properties. They are highly inhibited against moisture and rusting in both fresh and sea water and pass both A and B Sequences of the ASTM D-665 Turbine Oil Rust Test. Incorporating the super high viscosity index of the Stabilized* HOBS into the formula, gives multi-grade synthetic base oil performance by boosting the viscosity index (VI) past synthetic levels (energy conserving formulas). This super high viscosity index naturally improves the thermal shear stability of the formula and increases load capacity.
