Abstract
A method and system for the spray application of epoxy materials is provided. The system includes a dual walled tank structure as a reservoir for containing and preheating the epoxy materials in preparation for mixing and spray application. Each component of the epoxy material is preheated before the components are mixed. After preheating, the components are then mixed together and spray applied. The method and system of the present invention provides a high quality spray applied epoxy coating while reducing equipment down time and cleaning.
Claims10
A method of spray application for a multi-part epoxy material, said multi-part epoxy material including at least a resin and a catalyst, said method comprising the steps of:
- providing a heating tank having an resin chamber therein;
- filling said resin chamber with an epoxy resin;
- preheating said resin within said resin chamber to a first temperature that is below the evaporation temperature of the various chemical components within the resin;
- drawing said preheated resin from said resin chamber to create a resin flow;
- providing a catalyst;
- creating a catalyst flow within a closed environment;
- preheating said catalyst flow to a second temperature that is above the evaporation temperature of the various chemical components within the catalyst;
- mixing said catalyst flow and said resin flow;
- and
- discharging said mixed resin and catalyst flow at an elevated pressure.
