Abstract: Solvent-free spraying system including methods and apparatus for spraying plural component materials without requiring the use of solvents to flush out equipment or as part of the materials being dispensed. Materials sprayed can have simultaneously widely varying viscosities, pressures, temperatures and ratios between two or more respective components being combined by the spraying apparatus. Cure rates and gel times can vary widely from hours to less than 10 seconds for mixing and dispensing various plural component thermoplastic and thermosetting materials including foams, moldings and coatings made from urethanes, ureas, epoxies, polyesters, phenolics and other chemical compositions that react rapidly upon mixing of the components thereof.

Abstract: An apparatus for and method of coating the external surfaces of slender non-rotating members such as pipe, tube, rebar, wire, cable, coil springs, angle, channel, sheets, strips or bars as they are moving longitudinally through the coating apparatus with a fluid using a single-port or multi-port rotary union and one or more spraying orifices. The apparatus further includes the ability to apply either single component or plural component coatings to said non-rotating, moving members. Said coatings can include various types of paints, varnishes and thermoplastic or thermosetting single component or plural component coating products. Said plural component coating products can be made from urethanes, ureas, epoxies, polyesters, phenolics and other chemical compositions that react rapidly upon mixing of the components thereof. Said coatings can also include foam materials. Said fluid can be in liquid or powder form.
