According to Master Bond, its EP42HT-4AOMed Black epoxy adhesive withstands aggressive chemical sterilants, radiation, and repeated cycles of autoclaving.
Master Bond EP42HT-4AOMed Black is a two-part epoxy created for medical device manufacturing. It is reportedly biocompatible and non-cytotoxic, passing both USP Class VI and ISO 10993-5 certifications. The company reports that this epoxy withstands aggressive chemical sterilants, radiation, and repeated cycles of autoclaving.
EP42HT-4AOMed Black reportedly offers both cryogenic serviceability and heat resistance with a service temperature range from 4K to 400°F. Its thermal conductivity measures 9-10 BTU•in/(ft2•hr•°F), and its volume resistivity is greater than 1014 ohm-cm. The system contains a filler, which contributes to its high strength profile and dimensional stability. This adhesive bonds well to metals, composites, glass, ceramics, rubbers, and plastics. It features a tensile modulus of 500,000-550,000 psi, a compressive strength of 24,000-26,000 psi, and a tensile strength of 7,000-8,000 psi.
