Chemical reactions are inevitable in today’s surroundings. So many things we can’t even comprehend are floating in the environment. This is why corrosion should be preempted when painting. Almost all of us are familiar with rust. It is the most common form of corrosion. Protective coatings are your best defense against this.
There are several kinds of protective coating. They can either be metallic or liquid. They can be used in various fields such as building material, transportation, aircraft, industry and marine applications. Protective coatings are also divided into either maintenance or permanent.
Protective coating is a new technology brought to us by the advent of the very large scaling of transistors. Nanotechnology is what they call it. The coating makes the objects resistant to weather. We all know that water is the universal solvent and therefore it can interfere with the chemicals of the surface in due time or with constant exposure. The coating also transforms the surface and improves it making it easy to manage. Overall, its benefit is corrosion resistance and improved strength in various conditions. Apart from that, it is also environment friendly and easy to prepare. Since the development of nanotechnology is still rising, companies are investing on its research to a great extent.
An above standard type of protective coating is knows as barrier coating. It works as a protective film, filtering out foreign elements. It shields the surface to prevent the unwanted chemical reaction. These types of protective coatings are usually made of oil or solvent. Their primary job is to keep water and other ions from reaching the metal and reacting there. Nowadays, these water-based protective coatings have even been made more environment-friendly. Though they are cleaner than other types, it is still not widely used because solvent and oil-based protective coatings have use in larger industries.
Most producers give you lots of options. Some are plating, polishing and conversion coating. These services use various compounds such as Teflon to provide protection. Other materials used are enamel and aluminized primers, acrylics and polyurethanes. Listed below are specific applications of protective coatings in the fields mentioned earlier.
Aircraft applications
Air pressure is a huge problem in the industry. Protective coatings are essential to give strength to the entire aircraft. The coating also protects the aircraft from weather disturbances. Various coatings are also used in the interior. It is used to provide a glossy finish to the transport making it look appealing and professional.
Automobile applications
The use in automobiles is also somewhat similar to that of aircrafts. Protective coatings are essential to this industry since cars are used in our daily lives. It is prone to wear and tear and especially to the fast changing weather. The coatings are also helpful whenever repairs are performed. It makes the car look brand new and tougher than usual.
Marine applications
Like aircrafts, marine vehicles also experience problems with pressure. Below sea level, the pressure is very strong. Protective coatings give the added strength these vehicles need. Though the metal itself is already strong, no risk can be taken. Apart from the pressure, the metal is always in contact with water. As stated above, water will contribute to corrosion which is why said coatings are applied.
