Master Bond Supreme 17HTND-2, Master Bond’s latest product addition, 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 of 410°F (210°C). The product also meets NASA low outgassing specifications per ASTM E595 testing.
Supreme 17HTND-2 has reliable electrical insulation properties with a volume resistivity exceeding 1015 ohm-cm at 75°F (23.9°C). It possesses high bond strength properties with a lap shear strength of 1,900 psi – 2,100 psi and a tensile strength of 7,000 psi – 8,000 psi. It 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, the epoxy 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 four to six hours or 350°F for two to four hours. An optimal cure schedule is at 300°F (148.9°C) for four to six hours, followed by a post cure at 350°F (176.7°C) for eight to twelve hours. The product bonds well to a wide variety of substrates including metal, ceramics, composites and several plastics.
