Ensinger PEI
Momentive Performance Materials RTV511 Silicone Rubber Compound for Low Temperature Potting, Encapsulating and Sealing, White
Categories: Polymer; Adhesive; Thermoset; Silicone; Silicone, RTV, Adhesive/Sealant Grade

Material Notes: RTV511, RTV560 and RTV577 silicone rubber compounds are low 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.

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

Applications:

  • Cast-in-place heat shielding
  • Thermal insulation
  • Low and high-temperature bonding
  • Potting and encapsulation of electrical assemblies

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