Coating application methods dipping

The more automatic the method of coating application, the more economical and efficient it is, since automation lends itself more readily to more even coatings than do manual methods, e.g. large surface areas lend themselves more readily to spraying techniques, whereas open work structures are more suitable for dipping methods. The coating should also be applied to a specified minimum thickness which is adequate for the service conditions and life envisaged.

The properties of a typical Chevron sulfur composite are shown in Table I. One desirable feature is the low melt viscosity in the 250°-300°F range. This provides considerable latitude in the choice of application methods. Spray has proven to be effective for many uses. Brush, roller, and dipping have also been used for some coating applications. Most composites can be put into service immediately after application because they attain most of their strength and durability shortly after they solidify from the melt. 

The fluid vinyls are extremely versatile with respect to application techniques. Dipping is one of the earliest and simplest methods to apply a coating. Figure 5 illustrates a typical liquid vinyl process. In this case, it is designed to handle plastisols. 

The application of stains to substrates includes spray, flow, dip, roll-coat, or hand application, ie, bmsh or rag methods. The type of application method used depends on the function of the stain itself as well the type of product being manufactured. 

The layer thickness is determined by the preheating temperature, the heat content of the parts, the dipping time, and the coating powder. Parts with complicated shapes or with different substrate thicknesses are difficult to coat. The layer thicknesses obtained by the various application methods and the resultant use profiles are summarized in Table 8.7. 

Primer and adhesive application are generally accomplished by spraying, brushing, tumbling or dipping. Each different application method has its own strengths and weaknesses. The choice of the application method is dependent on the size and shape of the parts, the number of parts to be coated, and whether the part is to be wholly or only partially coated. 

Applications aircraft interiors, automotive fuses, coatings, coil bobbins, dip switches, fiber optics connectors, hollow fiber, integrated circuits sockets, medical applications (due to the resistance to different methods of sterilization), membranes, microwave cookware, multipin connectors, printed circuit boards, transformer wire coatings, sight glasses ... 

The application of a thin, imiform, and continuous layer of seed crystals on the support determines the successful synthesis of a thin, defect-free zeolite film. The simplest and most often used method is to apply seed crystals to the substrate with mechanical rubbing [14]. Slip-coating [15] and dip-coating [16, 17] the substrate in a suspension of zeolite particles, followed by drying and calcination, are also used to seed the support surface, but the process often has to be repeated a few times in order to ensure a sufficiently high coverage of the support with zeolite seed crystals. Electrostatic deposition involves chaise modification of the substrate surface by...
