About Powder Coating
Powder Coatings are Durable, Attractive, and Long-Lasting
Powder coatings are durable, attractive, scratch-resistant, long-lasting and environmentally responsible when compared to other finishes. Used for protective and decorative purposes, powder coatings are available in an almost limitless range of colors and textures, and technological advancements have resulted in excellent performance properties. While powder coatings are 100% solid with virtually zero VOC’s they are easy to apply and give you not only an attractive finish but a protection for asset for many years.
What are Powder Coatings?
Powder coatings are based on polymer resin systems, combined with crosslinkers, pigments, leveling agents, flow modifiers, and other additives. These ingredients are melt mixed, cooled, and ground into a uniform powder. A process called electrostatic spray deposition (ESD) is typically used to achieve the application of the powder coating to a metal substrate. This application method uses a spray gun, which applies an electrostatic charge to the powder particles, which are then attracted to the grounded part. After application of the powder coating, the parts enter a curing oven where the coating chemically reacts to produce long molecular chains, resulting in high cross-link density. These molecular chains are very resistant to breakdown. This type of application is the most common method of applying powders. Powder coatings can also be applied to non-metallic substrates such as plastics and medium density fiberboard (MDF).
Sometimes a powder coating is applied during a fluidized bed application. Preheated parts are dipped in a hopper of fluidizing powder, the coating melts and flows out on the part. Post cure may be required depending on the mass, temperature of the part and the type of powder used. No matter which application process is utilized, powder coatings are easy to use, environmentally friendly, cost effective, and tough! Durability.
Powder coating is a high-quality finish that is found on thousands of products you come across every day. It protects and beautifies anything from machinery, buildings, playgrounds, furniture to household items you use daily. Powder coatings are preferred because of their durable and attractive finish and are more resistant to impact, moisture, chemicals, UV light and extreme weather conditions. Plus, they are a great choice because of their environmental advantages
