EP&T MagazineElectronics Production / Materials bonding epoxy master-bond materials production sealing system
MASTER BOND Supreme 17HTND-2 toughened epoxy system for bonding and sealing applications is a true one component system, not premixed and frozen, with an unlimited working life at room temperature. Product 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. Product delivers 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 1,900-2,100 psi and a tensile strength of 7,000-8,000 psi. Product 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 suitable for applications where no flow is critical.
