Introduce
DELO-DUOPOX SJ8665 is a 2-component adhesive, derived from modified epoxy resin, cured at room temperature (accelerated when heated to +80oC), temperature resistant up to +180oC, and under packaging dual-bottles that are compatible with Automix dispenser.
Featured application
▪ Structural fixation adhesive, fixed product details;
▪ Bonding of electronic components, and metals, giving high compressive strength, and high-temperature resistance;
▪ Service temperature ranges from -40 ~ 180 °C, and may have specific limitations depending on the application;
