New Lap Shear Strength Results for PEEK to PEEK

Posted on 3/19/2019 11:47:04 AM By ASC

MasterBond has published test results reflecting the lap shear strength for PEEK to PEEK for several of its adhesives. The findings show that EP3RR-80 has the highest lap shear strength value of MasterBond’s single-component epoxy systems. Among its two-part epoxies, MasterBond’s EP31ND had the highest lap shear strength.



The company says that by publishing its findings, it hopes to help engineers evaluate adhesive choices, but it warns that lap shear strength is not the only factor to consider when choosing an adhesive. Factors such as thermal conductivity, viscosity, and more may affect adhesive selection. Thus, SUP12AOHT-LO may not have the highest lap shear strength, but it would be the best choice if thermal conductivity is required, while EP30-2 offers a lower-viscosity option.

The company advises product designers to consult its technical advisers when determining materials specifications.
