Abstract:
A traction fluid comprising:(A) 15 to 99 weight percent of at least one organic oil; and (B) 1 to 85 weight percent of at least one siloxane composition chosen from; (I) 33 to 80 mole percent units of formula (R3SiO1/2), 0.2 to 66.8 mole percent units of formula (RSiO3/2), and 66.8 to 0.2 mole percent units of formula (SiO4/2) having a viscosity of from 1.0 to 50,000 mPa.s at 40Â° C., where each R is independently selected from alkyl groups comprising 1 to 18 carbon atoms and aryl groups comprising 6 to 18 carbon atoms provided from 10 to 70 mole percent of R groups are not methyl; (II) 33 to 75 mole percent units of formula (R3SiO1/2) and 67 to 25 mole percent units of formula (RSiO3/2) having a viscosity of from 2.0 to 20,000 mPa.s at 40Â° C., where each R is independently selected from alkyl groups comprising 1 to 18 carbon atoms and aryl groups comprising 6 to 18 carbon atoms provided from 10 to 70 mole percent of R groups are not methyl; (III) 33 to 80 mole percent units of formula (R3SiO1/2) and 67 to 20 mole percent units of formula (SiO4/2) having a viscosity of from 1.0 to 70,000 mPas at 40Â° C., where each R is independently selected from alkyl groups comprising 1 to 18 carbon atoms and aryl groups comprising 6 to 18 carbon atoms provided from 10 to 70 mole percent of R groups are not metbyl; and (VI) cyclosiloxanes of formula (R2SiO2/2)a having a viscosity of from 2.0 to 50,000 mPa.s at 40Â° C., where a is an integer ranging from 3 to 20, each R is independently selected from alkyl groups comprising 1 to 18 carbon atoms and aryl groups comprising 6 to 18 carbon atoms provided from 10 to 70 mole percent of R groups are not methyl.
