Among many other application areas, the US Navy utilized this expl for salvaging ships sunk in harbors. They extruded the material from a caulking gun on the bead of a weld. When detonated, it would break the bead free from the plate, thus allowing salvage of the unscathed plate... 

These systems can be troweled on or extruded through a caulking gun. Little operator skill is required. Since the thixotropic nature of the paste prevents it from flowing excessively, application is usually clean, and not much waste is generated. With trowel application, the depth of notch and the spaces between them help regulate the amount of adhesive applied. Shallow, rounded, and closely spaced notches are often used with lower-viscosity adhesives to allow the lines of adhesive to flow together and form a continuous, unbroken film. 

A different extrudable explosive is available from NAX that is packaged in plastic mastic tubes (each containing 0.5 kg of explosive) to fit a standard caulking gun. This explosive is called DEMEX-400 and contains RDX and nonsetting plasticizer.

Cover the surface of the face of the panel backing with silicone caulk, in an even layer with no missed spots. The best way to do this is with your hands. Squirt the silicone from the caulk gun on to the panel back and them smooth it with your hands (see photos at right). Work quickly, because the layer of silicone is thin and will dry fast. Lay the screen in the... 

The epoxy polysulfide formulations are comparatively fast setting, with a short pot life. In filling a crack on a horizontal slab, the crack is widened by mechanical means to form a slight trough. The mixed compound may then be introduced into the crack by means of a caulking gun, or dispensed through a narrow spout. 

Adhesives are often classified by their mode of application. Depending on viscosity, adhesives can be coated, sprayed, or brushed. Adhesive pastes and mastics are applicable by extrusion and may be applied by syringe, caulking gun, or pneumatic pumping equipment. 

Caulking cartridge n. An expendable container made of plastic, fiberboard or metal, filled with caulking compound, for use in a caulking gun. A common type is 2 in. (5 cm) in diameter, approximately 8 in. (20 cm) long, and fitted with a plastic nozzle. 

Caulking gun n. A device for applying caulking compound by extrusion. In a hand gun. 

As the quantity of adhesives used increases, the small tubes can be replaced by air-operated caulking guns. These range in size from a few ounces up to a quart. Some of these systems utilize plastic cartridges that can be locally filled and, with proper cleaning, reused. While there are air-operated guns available that can be used in automated systems, this type of equipment is generally used directly by an operator. 

Some mortar joints, especially very narrow ones, may be sealed with an elastomeric sealant applied by a caulking gun. Cracked bricks may also be repaired by widening the crack and sealing it with an elastomeric sealant. 

Caulking Gun nA device for applying caulking compound by extrusion. In a hand gun, the required pressure is supplied mechanically by hand in a pressure gun, the pressure required usually is greater and is supplied pneumatically. 

Caulks and sealants made from the isobutylene polymer family are available in three forms. As bulk sealant materials, they are usually one-part, plasticized systems, compounded with suitable inert fillers and solvents and designed for application with a standard caulking gun. As preformed tapes or ribbon sealers, they are 100% solids, tacky materials, supplied in roll form on a release paper backing and designed for easy hand application in areas which usually require compressive confinement for an effective seal. Finally, in a newer format as 100% solids, hot melt compositions, they are specif-... 

Neoprene adhesives are conventionally applied by spraying, curtain coating, roller coating, brushing, or extrusion (i.e., by a caulking gun). Spraying is by far the most important industrial technique, as it permits rapid laydown of ad-... 

Tubes or Cartridges. These are filled caulking cartridges, typically 10.7 ounces to one quart, applied by hand or power-activated caulking guns.

Methods available for application. Any one of the preferred systems of application may have available a number of different systems of varying sophistication. Where an application would require extrusion, for example, a factory controlled situation may dictate a capital expenditure for automatic equipment. At the other end of the scale, the do-it-yourselfer would find a cartridge his best method of extrusion, with a caulking gun. Often an application system already in use can be...

Ideally, use a caulking gun, which allows you the best control for drawing a consistent, even bead. Most manufacturers also offer caulk in squeezable tubes, which are good for small jobs, and some caulks also come in aerosol form. Load the caulk into the caulking gun and cut off the tip of the tube at a 45-degree angle. Puncture the seal with a nail...

The method of application depends on the viscosity of the adhesive or sealant and the end-use. This can vary from DIY home projects to fast highly automated automobile production lines. Low viscosity adhesives can be brushed, sprayed, or pmnped through automated coating equipment, as in the encapsulation of computer chips with epoxy resin. High viscosity caulks and sealants can be apphed with a hand caulking gun or an automated caulking system or a simple putty knife.
