They are a low viscosity polydimethylsiloxanic fluids.
Details
Low Viscosity Silicone Oils
Description: They are a low viscosity polydimethylsiloxanic fluids.
Applications:
Low temperature hydraulic fluids;
Thinning agents for RTV’s and silicone sealants ( Two component, room temperature vulcanizing silicone elastomers);
Coating additive to improve flowablity.
Properties:
Very good heat stability,
Low surface tension,
High compressibility,
Good weathering resistance,
Good oxidation resistance,
Low freezing point,
Less change in viscosity as a function of temperature than non-silicone oils,
Good resistance to high and prolonged shear forces,
Low heat of combustion,
Limited combustion.
