Master Bond EP4G-80Med

Key Features

  • Good electrical conductivity
  • Flowable
  • Convenient packaging
  • Meets ISO 10993-5 certification

Master Bond EP4G-80Med is a one-component, low viscosity, graphite-filled epoxy. This material has exceptional flow properties and can be used for bonding, sealing, and coating applications. It combines good thermal and electrical conductivity. The epoxy is not premixed and frozen and has a working life of 8-12 hours at room temperature. It cures readily in 60-90 minutes at 80°C. Post curing at 80°C for 1-2 hours will optimize properties.

EP4G-80Med bonds well to a wide variety of substrates such as metals, composites, ceramics, and many plastics. It has a high tensile modulus and compressive strength. Its volume resistivity ranges from 50 to 100 ohm-cm. This conductivity profile allows the system to be used either for shielding or for bonding medical-type substrates where this kind of resistance is required. Graphite can be a desirable filler material because it is non-metallic, and provides fine performance and cost-effectiveness. EP4G-80Med withstands water and many aggressive medical sterilants. Its color is black. The service temperature range is -50°C to +175°C. EP4G-80Med is an attractive option for medical device applications where good electrical conductivity, easy application, and fast curing at lower temperatures is advantageous.
