Fast curing, silver filled epoxy meets ISO 10993-5 cytotoxicity standards
MASTER BOND EP77M-FMed two part epoxy adhesive and sealant is suitable for use in the assembly of medical devices. Product meets the ISO 10993-5 requirements and is not considered to have a cytotoxic effect. As a silver filled system, product has been formulated to provide improved electrical and thermal conductivity properties, while keeping in mind processing constraints for heat sensitive components in sensors used for medical devices or wearable electronics. Product delivers improved electrical conductivity, with a low volume resistivity of 10-3 ohm-cm, as well as a thermal conductivity of 1.44-1.73 W/(m•K), resists thermal cycling and has a Shore D hardness of 40-50 at room temperature. It can withstand exposure to water, liquid sterilants, anti-microbial disinfectants and EtO sterilization. It offers a tensile strength of 2,000-3,000 psi and a tensile modulus of 250,000-300,000 psi at 75°F. This system is serviceable over the temperature range of -100°F to +250°F.
