LOCTITE® 3621

Known as Chipbonder 3621

Features and Benefits

Electrically non-conductive adhesive for bonding surface mounted devices to printed circuit boards prior to wave soldering. Perfect where dispense speeds greater than 35,000 dots/h are required.
When you need a surface mount adhesive with very high dispense speed, try LOCTITE® 3621. It is specially designed for bonding surface mounted devices to printed circuit boards prior to wave soldering, and is ideal for applications where very high dispense speeds (greater than 35,000 dots/h), high dot profile, high wet strength, and good electrical characteristics are required.
