Powder coating is a type of coating that is applied as a free-flowing dry powder. The coating is applied electrostatically and is then placed under heat to allow it to cure and form a film. It is usually used to create a hard, durable finish that is tougher than conventional paint and more resistant to abrasion and corrosion compared to liquid coatings.
Yes. The powder coating application consists of dry matter only, and hence involves no emissions into water or air. Liquid paint applications require an evaporating VOC (volatile organic compound) and cleaning solvents. Our powder coating finishes can be used in all LEED-certified and green building projects.
We are surrounded by powder-coated parts: fencing, patio furniture, store shelving, metal furniture, light fixtures, appliances, and bridge materials are all examples of items that are commonly powder coated for superior corrosion resistance and durability.
There are several advantages to powder coating over conventional liquid coatings:
The two main types of powder coatings are thermoplastic and thermoset. In each of the two, there are a variety of subgroups. The most popular among thermosets are polyester and epoxy. Epoxy is best for indoor or chemical-resistant applications. It provides a hard, highly durable, and shiny finish. Disadvantages appear, however, when it is exposed to UV light – these items tend to chalk and dull over time. Polyester coatings weather well, look great, and are resistant to abrasions.
