Master Bond’s Supreme 17HTND-2 bonds well to various substrates including metal, ceramics, composites, and several plastics.
Master Bond‘s 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.
The new 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.
This toughened epoxy has reliable electrical insulation properties with a volume resistivity exceeding 1015 ohm-cm at 75 ° F. It possesses high bond strength properties with a lap shear strength of 1,900 to 2,100 psi and a tensile strength of 7,000 to 8,000 psi.
Supreme is designed to withstand thermal cycling and offers a wide service temperature range from -100° to +550° F (-73° 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.
The epoxy 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 for four to six hours, followed by a post cure at 350° F for eight to 12 hours. It bonds well to a wide variety of substrates including metal, ceramics, composites and several plastics.
Black in color, it’s available in standard packaging of jars and cans, ranging from 1/2 pint to gallon containers.
