Master Bond EP42HT-4AOMed Black is a new two-part epoxy created for medical device manufacturing. It is biocompatible and non-cytotoxic, passing both USP Class VI and ISO 10993-5 certifications. This epoxy withstands aggressive chemical sterilants, radiation and repeated cycles of autoclaving.
EP42HT-4AOMed Black offers both cryogenic serviceability and heat resistance with a service temperature range from 4K (Kelvin) to 400°F. Its thermal conductivity measures 9-10 BTU•in/(ft2•hr•°F) and its volume resistivity is greater than 1014ohm-cm.
The system contains a filler that 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 500,000psi - 550,000psi, a compressive strength of 24,000psi - 26,000psi, and a tensile strength of 7,000psi - 8,000psi.
This epoxy can cure at room temperature, but faster cures can be achieved by heat curing. Once mixed, this versatile adhesive has good flow properties, making it suitable for bonding, sealing and coating applications. Upon curing, EP42HT-4AOMed exhibits very low shrinkage, low exotherm and can be used for castings up to 2 inch – 3 inch thick. It is also available in pre-mixed and frozen syringes, which are compatible with automated dispensing equipment.
