Master Bond (Hackensack, NJ, US) reports that it has developed at two-part epoxy system for aerospace applications, called EP90FR-V. It has passed the vertical burn test portion of the FAR standard 14 CFR 25.853(a) for flame retardancy. Master Bond says this enables it to be used in aerospace interior panels, door frame lining and floor/door assemblies. EP90FR-V has a 1:1 mix ratio by weight and viscosity of 20,000-40,000 cps. This system is suitable for bonding, sealing, coating, potting and encapsulation applications. It is said to bond well to composites, metals, glass, ceramic and many plastics. EP90FR-V, which is non-halogenated, is serviceable of -51°C to 121°C. 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. It can be packaged in guns, FlexiPaks and premixed and frozen syringes. It is also available in standard packaging kits.
