The EP21TCHT-1 two-part cryogenic epoxy adhesive is for the assembly of difficult-to-bond substrates used in state-of-the-art wind tunnels. The epoxy has a 2,200-psi shear bond strength at ambient temperatures up to 400°F and low-temperature cryogenic environments down to 4°K. The bonds are resistant to thermal cycling and many chemicals. The high thermal conductivity of the hardened adhesive is useful in the tunnel’s overall temperature cycling performance.
