Our 3M Pneumatic Guns for 2-Part Cartridges are designed for dispensing 3M 2-part adhesives and sealers and come in two sizes compatible with 200 mL or 400 mL cartridges. Ideal for large volume jobs, they dispense a range of two-component repair epoxies quickly and smoothly, saving time and reducing rework. The snap-in cartridge system eliminates premixing and maximizes material use.
