Direct pressure apparatus and method for dispensing coatings

   
   

The invention is related to a coating delivery system that includes at least one pressure vessel operable in sealed and unsealed conditions, a deliverable substance including a coating component interspersed with at least one of liquefied carbon dioxide and supercritical carbon dioxide, and a pressurizing fluid. The deliverable substance is disposed in a first pressure vessel of the at least one pressure vessel, and the pressurizing fluid directly exerts a pressure on the deliverable substance to effect transport thereof when the pressure vessel is in the unsealed condition. The deliverable substance may be spray discharged.
