    Pneumatic Applicator Guns

    Pneumatic handguns are very convenient, and where a compressed air supply line is available), they reduce operator fatigue since the operator simply has to press a trigger to dispense material - avoiding the backpressure that is present with manual handguns. Pneumatic guns are more expensive compared to manual handguns. These are high quality professional tools that will provide years of service.

    • 250 ml 10:1 Pneumatic Handgun (shown at left) - #SS001-2P


    Manual Applicator Guns

    Manual handguns are desired in most situations, since they are portable (since no compressed air supply line is required), and they are more affordable. These are high quality, professional tools that will provide years of service.

    • 250 ml 10:1 Manual Handgun (shown at left) - #SS001-2
    • 10:1 Ratio Newborn Manual Handgun (not shown) - #SS005-N

    Static Mixer Tips

    Static Mixer tips are attached to the tip of the cartridge, and as the gun handle is depressed, glue and activator are extruded out of the 2-part cartridge, where they are mixed thoroughly in the static mixer tip as the two materials are driven through the tip. After passing through the static mixing tip, the fully mixed glue is dispensed at the tip of the static mixer tip.

    Available in three styles:

    • Static Mixer Tips for "new style" 250 ml 10:1 ratio cartridges - #SS250-S
