High oleic vegetable oils are sometimes to be preferred as base stocks for blending oxidation stable hydraulic fluids and lubricants intended for use in environmentally sensitive applications. A drawback, however, is that they are all of a similar light viscosity, only about 40 cSt at 40°C. FUNCTIONAL V- 516 is a thickener for high oleic vegetable-based oils, to blend lubricants of ISO 46, ISO 68 or ISO 100 viscosity grade. Functional V-516 does not make the lubricant tacky. Use FUNCTIONAL V-570 or FUNCTIONAL V-584 where the tackiness is desired. For lubricants using vegetable oil with normal oleic content V-515 is recommended.

COMPOSITION:
The active additive in FUNCTIONAL V-516 is a polymer selected for its shear stability and effectiveness in thickening. This polymer component is itself not readily biodegradable, but permits the viscosity adjustment of lubricants from biodegradable base oil systems. The diluent in FUNCTIONAL V-516 is a biodegradable vegetable oil. FUNCTIONAL V-516 is biodegradable under all widely used standards.

HANDLING:
While warming FUNCTIONAL V-516 to about 65°C (150°F) may facilitate pumping and handling, extended storage of this, or any other vegetable oil-derived product, at elevated temperatures is not recommended. Safe handling precautions are the same as those to be taken with vegetable oils; see the current Material Safety Data Sheet.
