Epoxy Adhesive for cryogenic applications


Many epoxies exhibit great performance at ambient and elevated temperatures. Even at lower temperatures most epoxies can perform adequately. With proper curing and surface preparation, EB-316M has a lap shear strength on aluminum of over 2500psi at -196°C (-320°F). Compared to standard epoxies such as 3M DP-460 or DP-420, EB-316M has far superior performance at cryogenic temperatures.

EB-316M is a 2-part, semi-flexible, room temperature epoxy adhesive. EB-316M is a semi-thixotropic material exhibiting extremely high bond strengths to metals, rubbers, glass, and many plastics.Used in a variety of industries including aerospace, industrial, and medical device, EB-316M is ideal for bonding and sealing dissimilar substrates. EB-316M is used as a high strength wire bond in gyroscopes of navigation units for aerospace components where temperatures can range from over 100°C to below -20°C. EB-316M also used to bond rubber sheaths around cast iron pipes that are exposed to temperatures above 250°C.
