Powder coating is a dry finishing process. It is different from a liquid coating. The difference is powder coating does not need a solvent to maintain the filler and binder parts in a liquid form. It is usually applied electrostatically. After that, it is cured with heat to form the coat. The finish it creates is a hard finish. It is tougher and harder than conventional paint since it creates a skin-like finish.
There are two types of powder coating. The first type is thermosets and the second is thermoplastics. The most general polymers used for this finishing process are commonly polyurethane, acrylics, polyester, polyester-epoxy, and straight epoxy. This finishing process is usually used for coating several different types of metals. They can be used for bicycle and car parts, as well as drum hardware or aluminum extrusions, and also for different kinds of household appliances. Many companies offer services for this type of services. One of them is the powder coating systems from Reliant which is one of the best. As far as advantages go, there are several. Here are a few advantages of powder coating:
Using this type of finishing process saves you time. It is very time-efficient. The curing times are a lot faster compared to the conventional processes. The drying time is accelerated by a significant amount of time. The processing time is also greatly reduced.
Better for the environment
First of all, compared to liquid coating, the powder is more energy efficient. The oven can recycle the hot air it uses more. It also requires less use of the burner. These things are what makes it save energy. On the other hand, liquid finishes contain solvents. These solvents have pollutants, which are called volatile organic compounds or VOCs. Since powder coating does not contain any solvents, it doesn’t release many volatile organic compounds into the atmosphere. Therefore, businesses can comply with the environmental regulations more easily.
The coats produced by powder coatings are a lot thicker than the conventional liquid finish. It produces a hard finish that does not run or sag. The items that are finished with this process commonly have fewer differences in appearance between surfaces that are coated vertically and horizontally. Another thing is it is quite easy to accomplish an ample amount of range in specialty effects when you use this type of finishing process, which would be quite impossible to achieve when you use other finishing processes.…
