Tested as per Amendment 25-116 and Part 25 Appendix F Passes horizontal burn test One to one mix ratio Withstands 1,000 hours 85°C/85% RH Master Bond EP90FR-HFL is a two component flame retardant epoxy system for bonding, sealing, coating and potting. It has been tested to the standards mentioned above and passes the demanding horizontal burn test specification. Thus, it can be considered for use in many specialized aviation applications. It should be noted that this epoxy is toughened and excels in withstanding rigorous thermal cycling as well as mechanical shock and vibration. Some of the uses include aircraft windows, lighting assemblies and baggage equipment areas, among others. Also, it should be noted that EP90FR-HFL is a non-halogenated type system, which is a big positive regarding handling and environmental issues. EP90FR-HFL has an easy to use, forgiving, one to one mix ratio by weight. This low viscosity system has a long open time with the recommended curing for optimizing properties being overnight at room temperature followed by 3-4 hours at 150-200°F. Since it is a top notch electrical insulator, it can be a candidate for electronic potting and sealing applications. It bonds well to a variety of substrates including metals, composites, glass, ceramic and many plastics. Since it has some flexibility, it is particularly useful for bonding dissimilar substrates. It has good chemical resistance to water, fuels and oils. The service temperature range is -60°F to +250°F. The color of Part A is black, Part B is white. When mixed, it will turn gray.
