SPRAY COATING PROCESS, ARTICLE AND ASSEMBLY FOR APPLYING ANY OF A POLYURETHANE OR POLYUREA COATING TO A WIRE HARNESS, FLAT OR IRREGULAR METAL SURFACE OR PLASTIC INJECTION MOLDED PALLET

摘要

A process and related assembly for applying a fast curing plastic spray coating to a substrate article having a specified shape and size with an exposed surface. The coating can include any polyurethane or polyurea composition and incorporating a fast curing catalyst which, upon delivery to a pneumatically charged nozzle, providing for aerated application from the nozzle upon the exposed surface. The spray coating further includes a cure time of between 5-10 seconds from aerated delivery and can be applied to any of a wire harness, metal surface or injection molded plastic pallet. In the specific instance of a wire harness coating. In the instance of a wire harness article, a plurality of branches terminate in end connectors, the coating providing insulating and fire-protection to the underlying harness.
