Ensinger PEI
Momentive Performance Materials RTV31 Silicone Rubber Compound for High Temperature, Red
Categories: Polymer; Adhesive; Thermoset; Silicone; Silicone, RTV, Adhesive/Sealant Grade

Material Notes: RTV31, RTV60 and RTV88 silicone rubber compounds are high temperature two-part silicone elastomers. They are supplied ready-to-use with a base compound and DEBT (deputy tin deflagrate) as the standard curing agent. DEBT is suitable for most applications, however other catalysts are available to facilitate deep section cure, faster cure and automated mixing.

RTV31, RTV60 and RTV88 silicone rubber compounds differ primarily in viscosity in the uncured state.

Mechanical and electrical properties for 0.5 wt% DEBT curing agent added, cured 7 days at 25°C and 50% relative humidity.

Key Performance Properties:

  • Variable work times and cure rates by adjusting the amount and type of curing agent
  • Room temperature cure
  • Composition free of solvents and solvent odor
  • Excellent adhesion capabilities with primer
  • Excellent release properties
  • Retention of elastomeric properties at temperatures from -54°C(-65°F) up to 260°C (500°F) continuously, and up to 316°C (600°F) for short periods of time

Applications:

  • Potting and encapsulating electric motors and transformers
  • Fabrication of rubber parts
  • Casting molds for low-melting point metals
  • Release applications such as rubber rollers
  • Thermal insulation

GE Silicones became a part of Momentive Performance Materials in 2006.
