Abstract: A cartridge assembly used with a conventional caulking gun for mixing and dispensing components of a material. The cartridge assembly includes a component carrying body that has a plurality of separate component reservoirs and a component flow directing housing at a forward end of the reservoirs. A mixing unit extends between the component flow directing housing and a discharge nozzle secured to the front end of the carrying body. The mixing unit mixes the components and delivers them to the discharge nozzle. The mixing unit includes a plurality of mixing cylinders that each have a longitudinal axis that extends substantially parallel to the longitudinal axis of the component carrying body. The mixing cylinders and guiding channels that extend between them form at least a portion of a component mixing path. The mixing cylinders can each include one or more mixing elements.

Abstract: A gasket or other comprising a core and a flexible outer layer prepared by co-dispensing at a temperature of about 15° C. to about 30° C., a core composition and an outer layer composition, wherein the core composition is an elastomer or a foam and comprises at least two reactive components, wherein each component has a viscosity at 25° C. of less than 106 cps. The core and outer layer compositions are applied in a non-solid state. The outer layer is preferably at least a two reactive-component elastomer or foam. A method for producing a gasket or other object comprising co-dispensing a core composition and an outer layer composition at a temperature of about 15° C. to about 30° C., wherein the core composition is an elastomer or a foam and comprises at least two reactive components, wherein the composition has a viscosity at 25° C. of less than 106 cps.
