Master Bond EP30-4Med is a two-part epoxy system with a fast set-up time that cures at room temperature — or even more rapidly with a bit of heat.
This low-viscosity system meets the requirements of ISO 10993-5 testing and is considered to be non-cytotoxic. It can be used for bonding, sealing, and small encapsulation applications. It can also be used as a coating, particularly when optical clarity is required.
EP30-4Med is designed to resist EtO sterilization and withstand most detergents, disinfectants, bleaches, and liquid sterilants. It’s recommended for applications in medical device manufacturing for disposable and reusable instruments.
Additionally EP30-4Med has an easy to handle 2-to-1 mix ratio by weight and possesses a low viscosity of 1,000-3,000 cps for Part A and 20-100 cps for Part B. Mixing is effortless, especially with the use of a double-barrel cartridge and static mixer.
This epoxy offers a relatively fast-setting system. Depending on the application and the substrates, fixtures often can be removed in 15 to 25 minutes. Full cure can be achieved in about 24 hours at 75° F. The ideal cure schedule is about one to two hours at 75° F followed by one to two hours at 135 to 150° F.
Upon cure, it exhibits a Shore D hardness of 75 to 85. The product is available in half-pint, pint, quart, and gallon kits. Specialty packaging is available in gun dispensers.
