For bonding applications requiring exceptional shear and peel strength, Master Bond Supreme 10HT delivers outstanding performance for both similar and dissimilar substrates. Supreme 10HT is a one-part toughened epoxy that offers lap shear strength of 3,400 psi and higher. Its fracture toughness and other mechanical properties are superior to those of standard epoxy adhesives due to the incorporation of a rubberized toughening agent.

Master Bond conducted lap shear testing with Supreme10HT for similar and dissimilar metals, and achieved a lap shear strength of over 3,400 psi for every combination of metal substrates (see graph below). These numbers were by far the highest among various other epoxies that were tested in comparison.
