Abstract
An applicator is provided which through the use of valve assemblies and separate first and second tubing member delivers two separate materials separately to a mixing head. The mixing head is provided with two separate passageways which terminate into an outlet passageway. To help create equal pressure between the materials at the point where the materials meet, an impinger can be placed in one or both of the mixing head passageways. Material flowing into each mixing head passageway first meet and are mixed in the outlet passageway. A tip is attached to the mixing head and a static mixer can be disposed within the tip for further mixing of the combined materials prior to their application out of the tip onto the intended surface. Material is supplied to the valve assemblies by various methods such as hoses.
