LOCTITE 3611 is a one-component, red epoxy adhesive designed for bonding surface-mounted devices (SMDs) to printed circuit boards before wave soldering. It provides very high wet strength and fast curing on high-speed SMT lines. Its low moisture absorption allows extended exposure to humidity without affecting dispensability or causing void formation.
