Silicones and Matthew Lindberg, Momentive’s Aerospace and Defense Technical Account Manager
comparing materials and applications for extreme temperature fluctuations and how to use new
delivery systems and assembly methods to save resources and time.

Topics covered include:

• Overview of silicones, epoxies and polyurethanes used for thermal protection in space
• Meeting ASTM E595 low outgassing requirements for adhesives in crew capsules and satellites
• Review of adhesive and sealant products and their application for the extreme temperature
  fluctuations encountered in reusable launch vehicles
• Leveraging new delivery systems to save manufacturing resources and time
