Corrosion-resistant coatings are protective layers applied to materials, particularly metals, to prevent deterioration caused by environmental factors like moisture, salt, and chemicals. These coatings can be made from various materials, including epoxy, polyurethane, and zinc, each offering different levels of protection and durability. These coatings work by creating a barrier that isolates the underlying material from corrosive elements. They are commonly used in industries such as construction, automotive, and marine, where exposure to harsh conditions is frequent. Proper application and maintenance of these coatings can significantly extend the lifespan of structures and equipment.
