Functional coatings

Optically Functional. Laser optics, layer architectural glass panels (up to 3 x 4.3 m), lenses, TV-camera optical elements, and similar apphcations require optically functional coatings. 

The volume of thermosetting powders sold exceeds that of thermoplastics by a wide margin. Thermoplastic resins are almost synonymous with fluidized-bed appHed thick-film functional coatings whereas thermosetting powders are used almost exclusively in electrostatic spray processes and appHed as thin-film decorative coatings. 

Thermoplastic polyesters achieved some commercial success during the mid-1980s however, these were eventually replaced by nylon coating powders in functional coatings and thermosetting polyester powders in decorative appHcations because of lack of any unique characteristics or price advantages (see Polyesters, thermoplastic).

Functional Coatings. Whereas there are many types of functional coatings, the basic properties or characteristics that give a device utility are its electrical, magnetic, and optical properties. The electrical properties can be defined by the ability of the material to conduct or hinder flow of electrons. This characteristic resistance is expressed by... 

In addition, all of the process raw materials must be clean and not iatroduce contaminants. The raw materials and temporary coatings must also be defect-free, and these have to be manufactured under similar conditions so that no contaminants are iatroduced. The solvents used to clean the substrate and develop the resists must be filtered and pure. Care must also be taken to ensure that no trace compounds or elements are present that may affect the electronic properties. The specific type of coating aid, the type of functional coating, and the process used to apply the functional coating are all widely varied ia actual practice.

In the light of the work presented in the foregoing from both the theoretical and experimental viewpoints, three concepts of engineered interfaces have been put forward to explain the roles of the thermoplastic coating, and their physical/ chemical requirements for three different functional coatings are proposed by Kim and Mai (1996b) ...
