TECHNICAL DATA & INFORMATION – Click to view complete technical

  • Low modulus silicone adhesive
  • -110ºC to 260ºC operating range
  • Low outgassing/space grade
  • Electrostatically Discharging (ESD)


APTEK 2717-A/B is a two component, black, low modulus, thixotropic, silicone adhesive displaying very low temperature flexibility and good physical strength properties.

APTEK 2717-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.


  • Utilizes silicone technology providing very low Tg for excellent low temperature performance
  • Convenient 10:1 PBW or PBV mix ratio for easy handling – ideal for cartridge dispensers/repair kits
  • Very flexible/low modulus over wide temperature range to absorb stress build-up during thermal cycling
  • Very good adhesion to various substrates when used in conjunction with MOMENTIVE SS4155 primer.
