Two-Component Cartridges and Static Mixers

The two-component products (structural epoxydes, polyurethane adhesives and sealants, other two-component sealants) may be extruded from two-component cartridges (Fig. 15) and then mixed in a mixing device called static mixer immediately at the exit of the cartridge. 

It is possible to use an air pressure gun, fed with a pump (Graco, De Vilbiss, Kremlin) that pumps the adhesive or sealant from a 20 or 200 litre drum and extrudes it with a hand gun. This allows much faster application and much larger output. We will study this system in the Section 2.6.
