MASTER BOND: Epoxy Adhesive/Sealant

November 15, 2010

The new EP21TDCHT-LO two-part epoxy adhesive/sealant is formulated for demanding applications where factors like temperature cycling, high vibration and mechanical shock are an issue. The material can withstand cryogenic temperatures and meets NASA low outgassing specifications. The system can be used in many structural, electronic, aerospace, medical, and oil and chemical processing applications.

As a toughened system, EP21TDCHT-LO is suited for bonding dissimilar substrates, especially when they have differing coefficients of expansion. It has an outstanding service temperature range from 4K to more than 350ºF. The material has a shear strength exceeding 2,500 psi, a peel strength of greater than 20 pli, and a shore D hardness of greater than 60. The cured epoxy offers chemical resistance and is an electrical insulator.
