Notice
  • Functional V-705 is intended for lubricants operating within temperature ranges from “average” (70-100°C / 158-212°F) to “very low” (<-34°C/-29°F) as defined in ISO 6743-6 guidelines. 
  • Functional V-705 is not recommended for use in lubricants or greases operating in continuous service >120°C/248°F ("very high"). This includes engine or crankcase oils, automatic transmission fluids, clutch fluids, and other lubricants under severe thermal loads. 
  • Very high temperature testing (methods like CEC L-60 and CEC L-37) may produce inadequate results in viscosity change and precipitation number. Testing at intermediate temperatures of 120-135°C (250-275°F), in ASTM D2893 and D2070 for example, is best when limiting total sulfur in the formulation to < 1.0wt% for 121°C and ideally < 0.50wt% for 135°C. Inactive sulfur packages are recommended where possible.

Technical Details & Test Data

Treatment Level
  • Functional V-705 is compatible in petroleum oils (Group I-III and naphthenic), PAO, vegetable oils, polyol esters, diesters, and estolides. Functional V-705 is compatible in low viscosity oil soluble (OS) PAG fluids but not WS or WI grades.
  • Treatment levels of 2 - 20% are typical in industrial lubricants and greases.
  • Functional V-705 can be used as either a VI improver or a shear stable base stock depending on the need. See next page for starting formulas. Functional V-705 is not suggested for very high temperature service. See next page for more information. 

Storage & Handling

Storage and Handling Information
  • Dissolving is best accomplished with continuous agitation at temperatures of 104-140°F (40-60°C). Functional V-705 may be preheated in a hot room or tank at up to 176°F (80°C) to aid in pumping but long term storage should remain below 140°F (60°C).
  • Functional V-705 is a non-hazardous material;
