Low Outgassing

Silicone RTVs for Low Outgassing Applications

Advanced silicone products that can deliver outstanding performance with minimal outgassing

Since the beginning of time, people have looked up at the stars and longed to explore the world above them.  For more than 60 years, Momentive has been part of the journey into space—providing the silicone in the boots of the first astronaut to walk on the moon—in the rockets that propelled those pioneers into orbit—and on every US manned space flight since. Building on the legacy of our past, Momentive continues to develop innovative silicones that help today's aerospace pioneers reach ever greater heights. From launch to landing, Momentive's advanced silicone products enable the next generation of space exploration.
