The biggest disadvantage to two-component side-by-side cartridges is the need for special dispensing guns. TAH Industries has solved this problem with a new two-component cartridge design. The patented Universal Cartridge fits into a standard caulking gun and stores one component of the adhesive in front of the other -- but both are extruded through the cartridge outlet and into a static mixer simultaneously. The cartridge is robust in order to maintain a very accurate volumetric ratio, and it eliminates bulging or expansion of the cartridge. The 1:1 ratio contains 250 mL of usable material, and the new 2:1 ratio holds 177 mL.
