1.2.1 Description/applications

Silicone 200 is a good general purpose fill fluid for industrial applications and is used in over half

of all remote seal assemblies. 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.

Silicones provide excellent thermal stability and low vapor pressure
