Anti corrosion
Encyclopedia
Anti-corrosion refers to the protection of metal surfaces from corroding in aggressive (corroding) environments.
When the metal material put into the corrosive environment, itself would have chemical reaction with the air. It brings corrosive phenomenon on its surface. For example, after putting the iron into the corrosive atmosphere for a long time, the iron starts rusting due to oxygen interacting with water on the iron's surface. Therefore, when normal electronic equipments which aren’t doing any preventive measurement, they may become rusted inside and outside of the metal housings for long time exposure. In order to prevent the corrosion, there are some ways for electronic equipments especially for marine application. For those electronic equipments where installed in salty and misty cabins are especially needed anti-corrosion measurements.

The main difference between a conventional liquid paint and a powder coating is that the powder coating does not require a solvent to keep the binder and filler...
on a metal’s surface. The function of this coating is to act as a barrier that prevents from either chemical compounds or corrosive materials from contact to the metal housing.
