Title:
SILICONE GREASE COMPOSITION
Document Type and Number:
Japanese Patent JP2669993
Kind Code:
B2
Abstract:
PURPOSE: To obtain a sticky grease having good heat resistance and good lubricating properties without adding any thickener by mixing a specified perfluoroalkyl-modified silicone oil with a specified powdery organopolysiloxane in a specified ratio.
CONSTITUTION: This composition is prepared by mixing 100 pts.wt. perfluoroalkyl-modified silicone oil represented by the formula (wherein R1 is a 1-10C perfluoroalkyl; R2 is a monovalent group selected from among a 1-12C alkyl, alkenyl and (substituted) aryl; a and b are each 0 or 1; m is 0-1000; n is 5-1000; m+n=5-1000; and R1 accounts for 5-50mol% of the total substituents) and having a viscosity of 100-100000cSt at 25°C with 20-3000 pts.wt. powdery organopolysiloxane having a molar ratio of R33SiO1/2 units (wherein R3 is an alkyl, alkenyl or aryl) to SiO2 units of 0.5-0.95.
