Master Bond EP3HTND-2Med Black is a high strength, fast curing epoxy for use in the assembly of medical devices. It fully meets USP Class VI specifications. This one part system delivers superior resistance to a variety of sterilization methods such as chemical sterilants, EtO, radiation and especially autoclaving.
As a one component system, EP3HTND-2Med Black does not require any mixing and essentially has an unlimited working life at room temperature. This epoxy has a paste consistency and is formulated not to flow while curing. It cures within minutes when heated at 250-300°F. The higher the temperature, the faster the cure speed. Also, it has low shrinkage upon curing.
This system bonds well to a wide variety of substrates including glass, metals, ceramics and most plastics. EP3HTND-2Med Black features a tensile strength of 5,000-6,000 psi and a tensile lap shear strength of 1,600-1,800 psi at room temperature. It is a competent electrical insulator with a volume resistivity exceeding 1014 ohm-cm. The service temperature range of this compound is -60°F to +400°F [-51°C to +204°C]. EP3HTND-2Med Black is available in ½ pints, pints, quarts, gallons and 5 gallon containers as well as syringes. This epoxy has a 6 month shelf life when stored at room temperature in its original, unopened containers.
