Adhesive Bond Strength: epoxy
structural high strength to underfill electronics
Adhesive bond strength data — lap shear strength, peel strength, service temperature, cure conditions, and substrate compatibility by adhesive type and variant. Covers epoxy, acrylic (methacrylate, cyanoacrylate), polyurethane, silicone (RTV, structural glazing), anaerobic (threadlocker, retaining, gasket), and phenolic/modified phenolic adhesive systems.
