Air-powered two-part adhesive applicators dispense two-part adhesives that bond materials together. Also known as 2K epoxy guns, they hold dual-cartridge adhesives (one resin component and one hardener component) that mix together as they are dispensed. They apply a smooth, continuous bead to minimize waste and form consistent seals. These two-component guns are commonly used to apply adhesives in structural, automotive, electronics, and manufacturing applications. Air-powered applicators run on compressed air and contain few moving parts, so they typically run cool, have a long lifespan, and weigh less than cordless applicators.
