Method of producing a multi-patterned coating

摘要

A multiple nozzle coating apparatus and method which simultaneous propels a plurality of coating compositions in substantially overlapping coating patterns. The coating compositions are formulated with a viscosity and rheology control agent to have sufficient wet strength to stand alone and not flow or readily mix with itself when applied under non-atomizing conditions. A separate nozzle is provided for each of the viscous coating compositions configured to create overlapping coverage over the area coated. The separate coating nozzles are inclined toward a substantially overlapping coat pattern. The coating compositions and compressed air are delivered to the separate nozzles. Adjustable valves are provided for releasing coating compositions and the compressed air from each of the nozzles to simultaneously propel coating compositions away from each of the nozzles to form a coat pattern wherein the coating compositions remaining substantially separate after being propelling.
