Polarizations of metal and metal composition are also important factors to be considered while selecting these methods for metal protection. And thus; the most promising and effective solution to protect the metal against corrosion left with engineers is an application of corrosion resistant coatings/protective coatings on metal surfaces. The applied corrosion resistance coating provides the barrier to external corrosive medium/agencies to reach up to metal surface and thus avoid the corrosion to occur. Applied coating also resists the spread of corrosion on the metal surface Various industrial sectors are using protective coatings for their jobs to protect them from the corrosion. Industrial sectors which involves use of heavy amount of protective coating includes oil and gas sector, marine sector, power sector, transport sector.
