Lap Shear Strength of Adhesives for PEEK | MasterBond.com

A variety of Master Bond products were tested for their lap shear strength for PEEK to PEEK, with the results displayed below. In order to perform this test, 4 x 1 x 1/16 inch coupons were roughened and cleaned with Isopropyl alcohol.

Graph 1 depicts Master Bond one component epoxy systems. Among these one part epoxy systems, EP3RR-80 has the highest lap shear strength value.

However, when choosing the proper adhesive, strength properties are not the only factors to take into consideration. Specific processing and operation conditions must also be kept in mind. For example if thermal conductivity is needed, SUP12AOHT-LO may be desirable. If a lower viscosity is needed, EP30-2 may be more suitable.
