Tough epoxy withstands cryogenic temps

摘要

The two-part EP21TDCHT-LO epoxy meets NASA low outgassing specifications and is specially formulated to withstand cryogenic temperatures, high vibration, and mechanical shock. The epoxy can bond dissimilar substrates, especially when they have differing coefficients of expansion. Service temperature range is 4 K to350℉, shear strength exceeds 2,500 psi, peel strength is ≥ 20 pli, and Shore D hardness is ≥60. Available in half pint, pint, quart, one-gallon, and five-gallon containers.
