MASTER BOND EP40Med two component, biocompatible, two-part epoxy system is formulated for medical device manufacturing applications. Product combines toughness and a low tensile modulus, while still providing a relatively high lap shear strength. Product meets the requirements of ISO 10993-5 testing and is therefore considered to be non-cytotoxic. Compound can be used for bonding, sealing, coating and encapsulating. Product resists sterilization to gamma, EtO, chemicals, and liquid disinfectants. The formulation bonds well to polycarbonates, acrylics, metals, ceramics and composites. This flexible epoxy has an elongation of 80-90%, a lap shear strength of 1,600 to 1,800 psi and a low tensile modulus of 25,000 to 50,000 psi.
