Dip coating is an industrial coating process which is used, for example, to manufacture bulk products such as coated fabrics and condoms and specialised coatings for example in the biomedical field. Dip coating is also commonly used in academic research, where many chemical and nano material engineering research projects use the dip coating ...
Conformal coating is a protective, breathable coating of thin polymeric film applied to printed circuit boards (PCBs). Conformal coatings are typically applied with 25–250 μm [ 1 ] thickness on electronic circuitry to protect against moisture and other substances.
The process is normally automated and requires less human labor than other coating processes. Highly efficient utilization of the coating materials result in lower costs relative to other processes. The aqueous process which is commonly used has less risk of fire relative to the solvent-borne coatings that they have replaced.
Electrostatic coating is a manufacturing process that employs charged particles to more efficiently paint a workpiece. Paint, in the form of either powdered particles or atomized liquid, is initially projected towards a conductive workpiece using normal spraying methods, and is then accelerated toward the work piece by a powerful electrostatic charge.
One such example is the formation of silver chloride on silver wire in chloride solutions to make silver/silver-chloride (AgCl) electrodes. Electropolishing , a process that uses an electric current to selectively remove the outermost layer from the surface of a metal object, is the reverse of the process of electroplating.
The coating penetrates better into pits and crevices. A uniform thick coating is produced, reducing the number of coats required. A very "wet" coating is applied, ensuring good adhesion and flow-out. Most coatings can be sprayed with very little thinner added, thereby reducing drying time and decreasing the release of solvent into the environment.

Spraying. The coating material is applied to the parts' surface using a spray gun. This can be done manually or in a fully automated spraying facility (this process is used for larger or unwieldy parts, also termed rack parts, as they are brought into the coating process on a rack). Dip-spinning. The parts get loaded into a basket.
