Silicone 200 is a good general purpose fill fluid for industrial applications and
is used in over half of all remote seal assemblies. Silicone 200 is made up of a
mixture of linear polymers with an average viscosity of 10 cs. This fluid has a
broad temperature range to cover ambient and process conditions and has a
low viscosity for good time response. Silicone fluids have a unique
combination of properties that give superior performance in a wide variety of
applications. Silicone fluids are quite different from other fluids.
