Triglyceride oils are sometimes to be preferred as base stocks for blending 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-515 is a thickener for vegetable-based or animal-based fatty oils, to blend lubricants of ISO 46, ISO 68 or ISO 100 viscosity grade. Functional V-515 dose not make the lubricant tacky. Use FUNCTIONAL V-570 or FUNCTIONAL V-584 where the tackiness is desired. For application requiring higher oxidative stability FUNCTIONAL V-516 is recommended.

COMPOSITION:

The active additive in FUNCTIONAL V-515 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-515 is a biodegradable vegetable oil. FUNCTIONAL V-515 is biodegradable under all widely used standards.

HANDLING:

While warming FUNCTIONAL V-515 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.
