TAH Industries has developed a new two-component cartridge platform that is significantly different than the cartridges commonly used today. The Universal Cartridge is a two-component cartridge that fits in a standard single-component caulking gun and has a capacity of 250 ml in a 1:1 ratio, and 180 ml in a 2:1 ratio.
The idea driving this concept is the requirement for special tools to dispense two-component adhesives and sealants, a hurdle that some potential users never overcome. The added cost and inconvenience of procuring the tool causes some potential users to shy away from what would otherwise be the best product for their application. Some two-component products are not penetrating their potential markets as deeply as they could because of their need for a special side-by-side dispensing tool. Other markets are not accessible to two-component products in their current side-by-side package, such as the DIY and home-improvement markets.
The TAH Universal Cartridge was created to enable adhesive manufacturers to break through the side-by-side dispenser barrier without sacrificing cartridge capacity and convenience when dispensing and mixing two-component adhesives and sealants. The new cartridge can be re-closed if the application requires only a portion of its contents. The cartridge outlet will accept industry standard static mixers, available in many sizes to meet the specific requirements of an adhesive system.
The Universal Cartridge stores one component of the adhesive in front of the other, but both are extruded through the cartridge outlet and into the static mixer simultaneously. The rear piston remains stationary. As the figure on p. 21 shows, when the inner cartridge is pushed forward, the red fluid is extruded through the center tube and out through the cartridge outlet. The front piston is pushed forward as the inner cartridge moves forward, causing the blue fluid to be extruded through the cartridge outlet at the same time.
Other products on the market designed to allow two-component materials to be dispensed with standard caulking guns include the following.
Filling the Universal Cartridge is also streamlined; all pistons are pre-inserted, and the entire cartridge assembly is leak-tested as part of the manufacturing process.
To determine if the Universal Cartridge is the right package for your product, you must first determine if your target market will place value on the ability to dispense your product without the need for a special dispensing tool. If it will, you must evaluate available cartridge systems based on the following criteria: Can the cartridge system contain your adhesive product reliably? Can the cartridge system hold enough material to serve the needs of your target market? Does your application require accurate volumetric ratio control?

U.S. Anchor, a Pompano Beach, FL-based adhesive anchor manufacturer, has set out to increase its penetration into this market segment. Contractors are finding it advantageous to make use of the caulking guns they already own rather than having to purchase additional special tools when they need greater flexibility or capacity. U.S. Anchor has also found that there is a significant untapped market segment made up of small contractors and homeowners who find the high cost of special dispensers prohibitive.
Steve Shade, vice president of U.S. Anchor Corp., says, "We call the revolutionary cartridge system EZ-Mix because it is just that simple and easy to use. For the first time, a homeowner can purchase our high strength Ultrabond Epoxy in a single cartridge and use it without pumping or hand mixing."
