Abstract

PURPOSE: To obtain a fluid composition suitable as brake fluid for automobile, etc., which is excellent in rublicity, rubber rublicity, and cold resistance, from a mixture of a specific organic polysiloxane and a borate as the main components.
CONSTITUTION: A fluid composition is prepared 60W99.5pts.wt. organic polysiloxane (A) of the formula I (where R is methyl or phenyl and n is 5W200), e.g., polymethylsiloxane, polymethylphenylsiloxane, etc., and 40W0.5pts.wt. borate (B) of the formula II (where R' is a 4 to 12C straight or branched alkyl group), e.g., tributyl borate, trioctyl borate, etc., as the main components. The preferred values of n in te formula I, being of a correlation with viscosity, are those giving a viscosity of 20W100cst at 25°C.
