Momentive Performance Materials LVG342B Low Volatile Silicone Adhesive Component, Clear  (discontinued **)
Categories: Polymer; Adhesive; Thermoset; Silicone; Silicone, RTV, Adhesive/Sealant Grade

Material Notes: LVG342 low volatile silicone adhesive is a two component, thixotropic silicone adhesive that cures very quickly at elevated temperatures to a durable elastomer. LV342 was specifically developed for applications that are sensitive to volatile siloxane species. For many applications, LVG342 is able to provide a very low level of volatility and out-gassing without the need for an extended post-cure bake cycle.

Key Performance Properties:

  • Very low controlled out-gassing and silicone volatiles
  • Very fast cure at elevated temperatures
  • Primerless adhesion to many substrates
  • Outstanding compression set and CSR properties
  • Excellent dielectric properties
  • Ideal consistency for robotic dispensing
  • Extended operating temperature performance

Applications:

LVG342 low volatile silicone adhesive may be suitable for use in applications where the end-use application requires the high performance characteristics of a silicone, but is potentially functionally sensitive to low molecular weight, volatile siloxane species which may be released, via out-gassing, from a standard silicone polymer.

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