Master Bond (Hackensack, NJ) EP40TCMed is a two part, room temperature curing epoxy system that meets the requirements of ISO 10993-5 for non-cytotoxicity. It is thermally conductive, electrically non-conductive and can be utilized as an adhesive or sealant in various medical and wearable device applications. Specifically:
- This toughened epoxy delivers an elongation of 60-70%.
- It has good strength properties with a tensile lap shear strength between 2,300 and 2,500 psi, a T-peel strength of 40-60 pli and a low tensile modulus of 5,000-15,000 psi at room temperature, making it ideal for applications where low stress is needed.
- The system’s small particle size filler allows for effective heat transfer when applied in thin layers, lowering its thermal resistance.
- It is also capable of withstanding exposure to EtO, radiation and several sterilants, as well as anti-microbial cleaning agents.
After mixing, the epoxy has a moderate viscosity of 80,000-100,000 cps, which is useful for applications where some, but not too much flow is required. Upon cure, it has low shrinkage and a hardness of 70-80 Shore D. EP40TCMed comes in standard sized units of ounce jars, ½ pint, pint, quart, and gallon kits. It is also available in premixed and frozen syringes.
