No Caulking Gun Needed Easy, Consistent Dispensing Mold and Mildew Resistant Light Weight. Safe to Use The Clear Food Grade Silicone Aerosol Self-Propelled Can is the perfect bead dispensing aerosol can for a variety of materials! Most aerosol cans can take up to 9+ minutes to dispense and drastically slow down towards the end of the can. With the Aerosol Self-Propelled Can, you will have a faster dispense time which leads to a cleaner bead and less material wasted. Nitrogen is used to insure stability for moisture cure adhesives and caulks. It is safer than most other propellants used. The aerosol can is also made of a substantial double wall piston that keeps the propellant separated in both extreme heat and cold. Directions Cut the caulk tip off of the nozzle to the desired bead size. Push the nozzle over to the side which actuates the piston and dispenses the material out of the hole cut from the nozzle.
