PAINT or COATING for corrosion protection?

Corrosion protection

As a member of the Corrosion Protection team in the process industry, it comes as a responsibility to protect your assets at the right time with the right solution. The involvement of Paint or Coatings always plays an important role.

So, what is the difference?

It is an age-old question really, “What is the difference between paint and coating?” As experts in this industry, we would like to help you to understand exactly what is the difference, so that you can make the right decision.


The main purpose of painting anything is to improve the aesthetics (the look or beauty of something). Paint can be applied to a variety of surfaces using many different application techniques. While there are some protective qualities that come with painting anything, that is not the real purpose of paint. The result of applying paint is for any surface to temporarily look nicer, look more vibrant, appear cleaner, or seem newer than it did before paint was applied.

Dry Film Thickness: 50-100 microns


What paint cannot do is where coating steps in; PERFORM. The coating is painted with purpose. The end purpose depends on the coating system that is decided upon. Like paint, coatings are applied to a variety of surfaces using many different application techniques.

Dry Film Thickness: 100-1000 microns

Here are a few examples of the performance a coating system can provide that paint cannot:

  • color retention
  • flexibility and elasticity
  • waterproofing
  • water-shedding
  • breath-ability (permeable)
  • rust and corrosion containment and prevention
  • self-cleaning
  • anti-microbial

Coating can be paint, but paint cannot be a coating. The difference is performance.

If you only want to make your assets “look” better for a short time or you have lesser rate of corrosion loss, then paint might be a better short-term and cost-effective option. However, if you are interested in protecting the asset for many years to come then a coating would be the better solution.

An internal Coating for corrosion protection with a DRY FILM THICKNESS exceeding 1mm is LINING

Linings prevent corrosion in a wide range of difficult applications. Linings offer a number of benefits, including:

  • Chemical resistance
  • Low permeability
  • Physical durability
  • Economical installation
