What are the Different Types of Coating

Coating is a technique that involves applying a material (usually in a lubricant form) on to a surface for increased aesthetic appeal and protection against contamination, corrosion, and oxidation. , This process helps in enhancing the durability of the product.

Based on the applications, coating can be:

  • Industrial
  • Commercial
  • Architectural
  • Special Purpose

Various materials are used for the purpose of coating a particular object. Similarly, the technique of coating differs too based on the type of object, what material it is made from, and what the final applications of the object will be. Here, we will have a look at 3 main types of coating.

Types of Coating:

Following are the mostly used types of coating in various applications:

  • Phosphate Conversion Coating: This type of coating makes use of diluted solutions of phosphate salts and phosphoric acid as a lubricant to apply over steel parts. The lubricant can be applied on a surface with the help of sprayers or by simply immersing the product into the solution. This kind of coating is helpful in the prevention of corrosion.
  • Dry/ Solid Film Coating: Dry/ solid film coating is an advanced technique that makes use of dry lubricants for robust protection against corrosion, scratches, and contamination. Products that operate in extreme conditions (excessive vibration, sub-zero to 1200°F temperatures, strenuous environment, etc.) can operate exceptionally well when coated using this technique.
  • Thermal Spray Coating: One of the most advanced coating techniques in recent times, this type helps in hardening the surface of the object that needs to be coated. In this technique, chances of distortion of shape or dimensions of the object are nullified because of applying minimal heat. This technique is useful for industrial and commercial products that require excellent resistance against wear and rusting.

These types of coating are amply used in various industries as well as commercial establishments. You can select the best suited type for your coating needs based on the product you are using and your expenditure range.
