Master Bond (Hackensack, NJ) EP21FRNS-2 passes UL 94V-0 testing for flame retardancy in potting, encapsulation, and casting applications. This two part epoxy features a one to one mix ratio by weight and cures at room temperature or more quickly at elevated temperatures, says the company. EP21FRNS-2’s handling is further facilitated by color coding—Part A is black and Part B is off-white. This durable system bonds well to a variety of substrates including metals, glass, ceramics, and many plastics. It can also withstand exposure to a range of chemicals, such as water, fuels, lubricants, and acids. As per the UL 94V-0 specification, EP21FRNS-2 is serviceable over the temperature range of -51 to 90 degrees C. Featuring a moderate viscosity, this epoxy maintains its flow and is a reliable electrical insulator.
