Master Bond Supreme 17HTND-2 is a toughened epoxy system for bonding and sealing applications. It is a true one component system, not premixed and frozen, with an unlimited working life at room temperature. Supreme 17HTND-2 is thermally stable, featuring a high glass transition temperature (Tg) of 410° F (210° C). It also meets NASA low outgassing specifications per ASTM E595 testing.

Supreme 17HTND-2 has reliable electrical insulation properties with a volume resistivity exceeding 1,015 ohm-cm at 75° F. The epoxy possesses high bond strength properties with a lap shear strength of 1,900 psi to 2,100Source: Master Bond psi and a tensile strength of 7,000 psi to 8,000 psi. The system is designed to withstand thermal cycling and offers a wide service temperature range from -100° F to 550° F (-73° C to 288° C). Along with its simple handling properties, it has a paste consistency and is completely non-drip, making it ideal for applications where no flow is critical.

Supreme 17HTND-2 cures at elevated temperatures with cure schedule options including 300° F for 4 to 6 hours or 350° F for 2 to 4 hours. An optimal cure schedule is at 300° F for 4 to 6 hours, followed by a post cure at 350° F for 8 to 12 hours. It bonds well to a wide variety of substrates including metal, ceramics, composites and several plastics. Black in color, it is available in standard packaging of jars and cans, ranging from ½ pint to gallon containers.
