In addition, there are also four types of protective coatings for metal: barrier, inhibitive, sacrificial, and combination. Barrier coatings protect metal by preventing water, oxygen, and electrolytes from coming in contact with the underlying metal. Inhibitive coatings contain chemicals that hinder corrosion.
What are different types of coating?

How coating is applied?
A coating is a covering that is applied to the surface of an object, usually referred to as the substrate. … Functional coatings may be applied to change the surface properties of the substrate, such as adhesion, wettability, corrosion resistance, or wear resistance.
What are the four key components of protective coats?
The four elements of a protective coating
- Binder. The “binder” portion of a coating, along with the other liquid components making up the product, are known as the “vehicle.” NACE explains a binder as the “non-volatile portion of the vehicle of a formulated material.” …
- Pigments. …
- Additives. …
What are the three types of coating?
Coatings are varied, but primarily fall into three categories: Architectural, Industrial, and Special Purpose.
What is coating and its types?
Coatings are specified as organic or inorganic according to the nature of their binder. Organic coatings are those that have an organic binder. Inorganic coatings are those that have an inorganic binder such as a silicate.
What are the functions of coatings?
Traditionally, the primary functions of coatings are to protect and decorate substrates. More recently, growth has occurred in the research and development, as well as commercialisation, of coatings which have novel functions in addition to having traditional protection and decoration properties.
How are powder coatings applied?
Most powder coating is applied electrostatically. The powder is sprayed through an electrostatic or cornea gun onto a metal surface that is grounded. … The electrical charge given to the powder by the gun is attracted to the grounded surface of the metal.
Why is coating important?
Industrial coatings are the best way to keep a variety of surfaces safe. They prevent corrosion. … It can not only stand up to the processing material, but also prevent standard corrosion that may occur simply because of the material the machine is made from. They keep surfaces clean.
