Trimethylsiloxyterminated dimethyl diphenyl polysiloxanes that are available with various phenyl contents and viscosities. These fluids are most often used in high and low temperature applications to enhance temperature stability. Low temperature flexibility can be improved with phenyl contents of 3-8 mole %. Higher phenyl contents improve high temperature thermal stability.

Vinyl-terminated dimethyl diphenyl polysiloxanes that are available with various phenyl contents and viscosities. Phenyl contents of 3-8 mole % optimize low temperature characteristics. The higher phenyl content materials can be used for index matching which improves clarity. All of these polymers are used in addition curing formulations in which a platinum catalyst and silicon-hydride crosslinker are present.

Additives for the improvement of mechanical properties in high phenyl containing systems. The mechanical properties of the unfilled RTV are rather poor, therefore the properties are improved with the addition of appropriate fillers i.e. carbon black, fumed or precipitated silica and other fillers well known to formulators with expertise in compounding silicones.
