  • Very low stress Silicone Adhesive
  • -110°C to 260°C operating range
  • Low outgassing/space grade


APTEK 2712-A/B is a two component, white, very soft, thixotropic, electrically insulative, silicone adhesive displaying excellent flow temperature flexibility and unusually high physical strength properties.

APTEK 2712-A/B has been designed to fully cure at room temperature and can be accelerated with a brief low temperature cure. This 100% solids system has been manufactured with highly pure resins to minimize the occurrence of ionic contamination without outgassing during cure or service.


  • Very flexible/low modulus over wide temperature range to absorb stress build-up during thermal cycling.
  • Convenient 1/1 PBW or PBV mix ratio for easy handling-ideal for cartridge dispensers/repair kits.
  • Very good adhesion to various substrates when used in conjunction with MOMENTIVE SS4155 primer or Dow Corning’s 1200 primer.
