Fluorosilicone lubricant compositions

摘要

Fluorosilicone lubricants comprise (A) a linear and/or cyclic polydiorganosiloxane containing at least one silicon-bonded perfluoroalkylethyl radical with at least four perfluorinated carbon atoms, and an additive selected from 1) heat stabilizers that are reaction products of cerium compounds and alkali metal silanolates or organopolysiloxanes with aminophenyl or naphthylaminophenoxy groups and 2) powdered fluororesins as cold temperature additives.
