Coating systems are techniques used in covering flat and uneven surfaces on any material. The use of coating technology is always in agreement with the high quality standards set by most industries in coming up with the very best line of products. Diverse coating materials are used each of which possesses a characteristic that's beneficial to the needs of markets.
Coating materials
Coatings are made of biologically safe chemicals combined through scientific operations. Coating is generally done by pouring or spraying an absorbent non-metal over metallic surfaces. These nonmetal materials are protected from wear and corrosion. They also have electrical properties. In many situations, they're sprayed. They are applied thinly just to cover uneven spaces of the work piece. The application technique is vital to be mastered in order for the film to give the desired beauty that can last. However, coating may also be done through a machine. Four elements are needed in coating formulation: binders, additives, pigments, and carrier fluid.
The following are the types of coating materials:
- Polyester is considered the most popular polymer that adds resistance to paint coated steel. This material is elastic and formable and can be used in hot or cold climate.
- Matted polyester is a coating that has a high color retention property. It is preferred when gloss is not found to be important.
- The pural is characterized by a silky matted structural surface that is very resistant to temperature variations. Just like the matted polyester, this has high color retention and displays mechanical resistance.
- Acryl is a combination of varnish and paint. This coating material is not dependable for it can be ruined easily even upon installation. The color fades under the sun given a number of years of use.
- Plastisol is used each time a really heavy coating is desired. It's highly resistant to mechanical damages. It has a high corrosion resistance but its color retention is observed to be lower than that of the polyester. However, it is one of the best coatings for smooth surfaces.
- PVDF is a plastic material which is made up of polyvinylchloride and acryl. Of all the coating materials, this is considered as the most UV-radiation resistant. It does not easily fade. It is among the most corrosive coating material that gives a thin gloss finish.
What Is In A Coat?
The use of the various coating systems all provide for quality and safe production of goods. A coat, whatever material it is made of, is intended to protect the product from deterioration and other damages due by moisture and other environmental factors. Aside from that, the beauty of products is maintained through the application of coat by providing it with smooth, pin hole-free finish.
The use of spray in coating is the most widely used coating technique. Aside from ease of application, coating through the use of spray is among the most economical technique for it does not any longer require the use of other machines. Moreover, the simplicity of its technique allows for work perfection and work efficiency. That is why of the many coating systems being offered to industries, the use of spray gained the most popularity.
