Two Component, Epoxy System for Potting, Encapsulating, and Casting

Master Bond® EP21FRNS-2 is a two component, room temperature curing, flame retardant compound for potting, encapsulating and casting. Particularly noteworthy are its low smoke generation and that it contains a non – halogenated filler. It has a convenient one to one mix ratio by weight. EP21FRNS-2 offers exceptional durability, toughness and strength. It is remarkably resistant to thermal cycling and many chemicals including water, fuels, lubricants, acids, among others. As per the UL 94V-0 specification, this system is serviceable over the wide temperature range of -51ºC to +90ºC. It bonds well to metals, glass, ceramics and many plastics. To optimize its properties, the best cure schedule is overnight at room temperature followed by 2-3 hours at 150-200ºF. Its electrical insulation properties are excellent. This compound is color coded for easy mixing; the color of Part A is black and the color of Part B is off-white. This formulation is far more user friendly when compared to standard flame resistant epoxy systems. EP21FRNS-2 has wide applicability in the computer, aerospace and related industries.
