Anti-corrosion coatings protect the material from degradation due to physical contact or exposure to air, water, and chemicals. The coating acts as a barrier or sacrificial material. The advantages of corrosion coatings include increased lifespan, and reduced operating costs. It also imparts various beneficial properties such as increased gloss or color appearance, durability, increased hardness, increased durability, and abrasion protection. Corrosion can lead to increased monetary losses in the form of repair costs, cleanup costs and loss of revenue due to non-productive time. The cost incurred due to corrosion globally is US$ 2.2 trillion, which is over 3% of the world’s GDP and more than the GDP of India alone.
A major challenge to anti-corrosion coatings market is using of alternatives materials, which are Fiberglass Reinforced Plastic (FRP), polymers and thermoplastics. Usage of these metals eliminates the need for anti-corrosion coatings. Also, the key raw materials for coatings manufacture is from the oil industry. The unstable oil industry will affect availability of raw materials and manufacture of coatings.
Epoxy Coatings are largely used in construction industry due to toughness and long life span. Rapid urbanization in developing countries has led to a commercial and residential construction boom driving the epoxy coat market. Furthermore, environmental advantage of low VOC concentration has made it a prime candidate over other products. Polyurethane coatings provide excellent weathering properties and hence used in high wear and tear environment.
