Protective coatings is very popular for applications such as vehicle rusting, abrasive and harsh chemical exposures, oil-wet state and salt water cure-resistance

 

Protective coatings are applied to many types of metals to provide a barrier of protection against abrasive or hazardous substances. They are also used to prevent corrosion of the metal, from direct impacts with these materials as well as from ultraviolet radiation exposure.

These coatings protect against corrosion from water, oil, and other liquids. Coatings are generally made from either steel or aluminum with certain additives and can be applied to metals like stainless steel, copper, bronze, and stainless steel forgings. These coatings resist corrosion by forming a protective shield around the surface, which stops the material from being compromised. This is done by incorporating anti-corrosion additives into the protective layer to prevent the additive's molecules from bonding to the corroded metal, thereby preventing corrosion.

They have numerous benefits. By limiting the exposure of metal to an acidic environment, protective coatings are an easy way to prevent corrosion. Common corrosive agents are diesel, paint, bitumen, tar, and plastics. Certain coatings do not require painting and can instead be applied to metals in a powder form, with the coating then curing naturally over time. For surfaces that do not need painting, coatings such as Teflon-based coatings, polyurethane-based coatings, and certain polyester-based coatings provide a strong barrier against corrosion and are long-lasting.

The coatings contain different additives that include boron, titanium, zinc, and iron. The additives work by providing a layer of protection for the metal by forming a seal that is impervious to corrosion. The most commonly used additives are zinc and titanium. Other additives are usually a combination of zinc and titanium. There are many different forms of protective coatings; some use pigments, and others use additives.
