What’s the difference between coatings and protective coatings? Aren’t all coatings protective coatings? In the broadest sense that might be true. However, protective coatings are a particularly demanding segment of the paint and coatings industry where the primary function of the coating is to provide a performance that extends the life of a structure, vehicle or piece of equipment operating or residing in a relatively harsh environment.
The Merriam-Webster’s definition supports this view, defining a protective coating as “a type of paint, varnish or lacquer used more to protect than decorate.
Protective coatings are used to shield a wide range of structures and equipment, with the market segmented into several areas, including:
- Industrial maintenance (including refinery and petrochemical plants)
- Oil and gas exploration (including pipeline)
- Power generation
- Commercial architecture
- Water treatment
Most protective coatings are field applied after construction, employing multiple coating layers and high film thickness. However, some pieces are primed in the factory before being shipped to their final destination, where they are installed (constructed) and then given a final coat.
To be able to safeguard such a range of structures and equipment across these many areas, protective coatings have to meet a number of performance requirements. They have to resist corrosive attack, chemical attack, thermal degradation, fire and physical damage. Protective coatings are extremely valuable, given that the types of structures they protect are often very expensive, long-lasting and are required to maintain their structural integrity in extreme conditions—because failure to do so could result in critical damages or even loss of life. Protective coatings can also be smart coatings, being able to help predict and communicate when their ability to protect is coming to an end.
Global Markets for Protective Coatings
While Europe and North America represent significant size markets (approximately 20% and 15% respectively), the largest market is Asia. The Asia region represents approximately 60% of the protective coatings market. China alone represents almost two-thirds of the Asian market, equating to 40% of the global market. There is a plethora of protective coatings producers around the world, but the top 11 suppliers combine for 70% of the global market.
