Developed for speciality aviation applications, a two part epoxy system has been introduced by Master Bond. EP90FR-V passes the vertical burn test portion of the FAR standard 14 CFR 25.853(a) for flame retardancy, which enables it to be used in aviation applications including interior panels, door frame lining and floor/door assemblies.

The epoxy has a convenient one to one mix ratio by weight and a moderate viscosity of 20,000-40,000cps. Suitable for bonding, sealing, coating, potting and encapsulation applications, it bonds well to a variety of substrates including metals, composites, glass, ceramic and many plastics. As a non-halogenated type system, EP90FR-V has an excellent environmental profile, which allows easy handling, and is also a reliable electrical insulator.

EP90FR-V is serviceable over the temperature range from -60 to +250°F. Its Shore D hardness is greater than 75 and it offers excellent chemical resistance to water, fuels, oils and many common solvents. This system is colour coded, to facilitate mixing: Part A is black, Part B is white and the cured material is grey. For ease of application, it can be packaged in guns, FlexiPaks and premixed and frozen syringes. It is also available in standard packaging including ½ pint, pint, quart, gallon and 5 gallon container kits.
