may be accomplished by using many different structural variations that are still intended to be covered within the scope of the present invention further for purposes of the present application the term u201c spray application u201d refers to breakup of the material into small particles or droplets that are broadcast onto a substrate in a pattern such as a fan sheet or cone pattern that has a width at the point of deposition on the substrate that is many times the diameter of the spray nozzle opening spray application is therefore defined in a manner that is to be distinguished from u201c flowing u201d or u201c extruding u201d where the material at the point of deposition has a dimension that is about the same a the dimension of the opening accordingly as discussed above the present invention is directed to a method and system for spray application of high molecular weight polymeric thermal cure epoxy materials such as structural epoxy that handles the material at application temperature and pressure without requiring solvents or the like to reduce viscosity turning now to fig1 and 2 it can be seen that the system 10 of the present invention includes generally a heating tank 12 means for establishing a flow of epoxy resin 14 through the heating tank 12 means for establishing a flow of catalyst 16 thought the heating tank 12 means for mixing the flow of resin and catalyst 18 to form a multi part epoxy mixture and a discharge nozzle 20 for the spray application of the epoxy mixture onto a substrate surface the heating.
