The ASTM D4147-18 standard describes a standard method for applying uniform thin film coatings on flat plates using wire wound coating bars. The method involves pouring Coatings on the surface of flat plates and using coating bar uniform Spreader to simulate coating applications in the laboratory. The desired dry-film thickness can be obtained by controlling the combination of coating bars, the volumetric solids of the Coatings and the speed of the Spreader. This method is often used in laboratory simulation of roller painting films and provides experimental basis for uniformity and application effect of coatings.
