Two component flame retardant epoxy developed for aerospace industry

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

EP90FR-V has a convenient one to one mix ratio by weight and a moderate viscosity of 20,000-40,000 cps. This system is 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. It is also a reliable electrical insulator.

EP90FR-V is serviceable over the temperature range of -60°F to +250°F. Chemical resistance to water, fuels, oils and many common solvents is outstanding. Its Shore D hardness is greater than 75. This system is color coded, which facilitates mixing. The color of Part A is black, Part B is white and the cured material is gray. 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.
