What is a Dispenser?

A Caulking Gun is a hand operated or powered device used to dispense a sealant to seal gaps between two surfaces to prevent leakage. Typical examples of such applications include Windshield and Window glazing. Caulking gun also is known by a variety of other names in different parts of the world such as dispensing gun, sealant gun, silicone dispenser, applicator or a mastic gun, but the purpose of all of these is just the same, apply the sealant with minimum possible effort in a continuous bead. While many DIY and Industrial applicators are manually applied by pulling the trigger, powered dispensers such as Pneumatic and Battery-operated systems are gaining acceptance in a variety of applications due to ease of use and high extrusion speed without having to apply any hand force at all.

Frequently Asked Questions

What is a bead dispenser?

A bead dispenser or a caulking bead gun means that applicator is designed to dispense the adhesive or sealant only in the form of beads. These applicators are supposed to be used while keeping them very close to the substrate.

Of course the bead dispenser can also be used to apply small dots but they cannot be used to dispense fixed quantity of adhesive or sealant as in case of a potting application. Sometimes users try modify bead dispensers (for example Cox Airflow 3 and Cox Airflow 1 Pneumatic Dispensers) to apply fixed quantity of glue per shot. This is not a practically feasible output from a bead dispenser and adhesive quantity after every subsequent shot reduces.
