Toughened epoxy system meets USP Class VI specifications 17 January 2020

Master Bond EP30DPBFMed is a two part, flexibilised epoxy urethane hybrid system that can be used for bonding, sealing, coating, and encapsulation. It is formulated for disposable and reusable medical devices, meeting USP Class VI requirements while also complying with RoHS3 in accordance with the EU directive 2015/863/EU. EP30DPBFMed is resistant to thermal cycling and sterilization, withstanding exposure to gamma radiation, e-beam, EtO, as well as other liquid sterilants.

Its low viscosity of 3,000 cps to 6,000 cps for Part A, and 200 cps to 500 cps for Part B, makes it readily pourable and ideal for potting and casting. EP30DPBFMed has a long working life of 60 - 90 minutes per 100g mass at 75°F, and features a low exotherm during the curing process. The system contains no solvents or diluents.

Due to the addition of a urethane based flexibiliser, EP30DPBFMed offers both a higher abrasion resistance and a higher elongation when compared to a typical epoxy system. At room temperature, it has an elongation at break of 20% to 40%, and Shore D hardness of 30 to 50. It is useful in applications where low stress is important, due to its low modulus value. This compound is electrically insulative with a volume resistivity greater than 1014 ohm-cm. EP30DPBFMed is serviceable over a wide temperature range from cryogenic 4K to 250°F.

This formulation is available for use in a variety of standard packaging options ranging in size from ounce kits to gallon kits. Specialty packaging in premixed and frozen syringes, and gun applicators with double barrel cartridges is also available.
