One and two component high performance silicone formulations meet NASA ASTM E595 specifications. They exhibit high/low temperature serviceability and a soft durometer. Available in flowable and non-flowable paste viscosities these compounds offer good adhesion to metal, ceramic, composite, glass, rubber and many plastic surfaces.
Advantages of Low Outgassing Silicone Adhesives
These non-corrosive, low stress systems have excellent electric insulative properties and are employed in many sensitive optical, electro-optical, electronic, aerospace applications. They are also noted for their ability to withstand rigorous thermal cycling and shock. Products are vacuum compatible and are engineered to ensure long term durability in space environments.
