Coating aids

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. 

Hydrogenated vegetable oil type I is additionally used as the matrix-forming material in lipophilic-hased controlled-release formulations " it may also be used as a coating aid in controlled-release formulations.

Electrolytic cadmium coatings [25] have been widely used to protect fasteners, particularly for exposure in chloride environments. The lubricity of cadmium coatings aids in uniformly tightening threaded fasteners. However, use of cadmium is declining because of toxicity and environmental concerns.
