Master Bond EP93AOFR Two component thermally conductive flame retardant epoxy system
Categories: Polymer; Thermoset; Epoxy; Epoxy, Thermally Conductive

Material Notes: Key Features:
  • Tested as per Amendment 25-116 and Part 25 Appendix F
  • Passes horizontal burn test
  • One to one mix ratio
  • For bonding, sealing, coating and potting
Master Bond EP93AOFR is a two component flame retardant epoxy system for bonding, sealing, coating and potting. It passes the demanding horizontal burn test. EP93AOFR has an easy to use, forgiving, one to one mix ratio by weight. This system has a long open time. The recommended curing schedule for optimizing properties is overnight at room temperature followed by 3-4 hours at 150-200°F. It is a good thermal conductor while retaining a favorable electrical insulation profile. It bonds well to a variety of substrates including metals, composites, glass, ceramic and many plastics. The service temperature range is -80°F to +300°F. It has reasonably good chemical resistance to water, fuels, oils and many common solvents. The color of Part A is black, Part B is off white and the cured material is black. EP93AOFR is a specialty product that is used primarily in avionics. Electronic assemblies such as power conversion units, distribution instruments and cooling devices require first rate protection from flames and heat. They often need to transfer heat to avoid damaging components. EP93AOFR is highly effective in conducting heat and providing protection from flames. EP93AOFR is a non-halogenated system, which is highly desirable for handling and environmental issues.

Product Advantages:

  • Easy to use, forgiving 1:1 mix ratio by weight
  • Long open time
  • Good flow properties; can be used for potting
  • Favorable thermal conductor and electrical insulator
  • Bonds well to many different substrates
  • Passes the horizontal burn test
