Abstract: A cohesive coating composition (16) having differential adhesion properties is applied to window glass (12) without regard to covering adjacent trim material (14) which is to be subsequently painted. The DAC (differential adhesion composition) coating (16) is characterized by high adhesion to wood, metal, plastics and painted surfaces and at the same time by selective adhesion to glass-like surfaces, so that the coating composition (16) may be easily scraped, peeled, or otherwise lifted from the glass (12), together with any paint overlay thereon, after the painting operation of the window frame (14) is completed. When subjected to sheer forces of pulling and scraping, the cohesive properties of DAC coating (16) when considered in combination with a relatively low adhesion to glass, allows the coating (16) to be removed in long continuous strips rather than fracturing into small pieces.

Abstract: The present invention relates to a porous electrode wire for use in electrical discharge machining and the method of manufacturing the same. The wire improves the machining speed at least 15% compared with a conventional zinc coated wire, which results from an increased cooling ability of the wire with a cooling liquid because of the increase in the surface area of the wire having porous surface morphology. Since the surface of the porous wire presents uniform profile of outer periphery rather than surface protrusions, it does not affect machining accuracy. Further, the porous nature of the wire is expected to improve flushability during the electrical discharge machining, providing spaces to eliminate particles of the machining. Therefore, in accordance with the method of the present invention, a zinc coated wire having improved performance of machining speed and flushability compared with a conventional coated wire can be provided without additional processes.
