Cartridges for Storing, Mixing, and Dispensing Two-Component Materials

Typical problems associated with the metering, mixing, and dispensing of two-component adhesives can be overcome by prefilling the materials into two-compartment plastic cartridges. This cartridge system accommodates every material ratio and handles liquid to heavy-paste viscosity materials. By preproportioning both components in the cartridge, the correct ratio can be assured every time. Mixing within the same translucent self-contained plastic unit permits thorough and consistent mixing of the reactive components. Contamination of the materials is avoided by premeasuring the materials into the cartridge. With prepackaged materials, personnel exposure to the materials and fumes can be eliminated or significantly reduced. The adhesive can be mixed and dispensed onto a substrate more efficiently and effectively than by conventional means.
