The "Anti-Drip" function of the extrusion gun prevents spontaneous leakage of sealant or silicone from the cartridge after the trigger is released. When the user stops pulling the trigger, the gun mechanism automatically pulls back the push rod slightly, which puts pressure on the cartridge plunger. This backward movement immediately releases the pressure inside the container and the flow of material stops immediately. The result is a clean finish without dripping and wasted material, eliminating the need to constantly wipe the application tip.
