Two types of powder coating
Powder coatings can be classified into two main categories: functional coatings and decorative coatings. While both types can add value to a product, each has unique qualities that make it appropriate for specific use cases.
Functional powder coatings
Functional powder coatings improve the functionality of a product by making it more durable and resistant to corrosion. Those qualities make functional powder coatings ideal for outdoor applications such as in the marine and architectural industries. Functional coatings are available in a limited set of color options and gloss levels.
Decorative powder coatings
Decorative powder coatings are designed to make products look more appealing by enhancing their color, gloss, and texture. Those qualities can be desirable for nearly any public-facing item so decorative powder coatings make up the majority of modern powder coats and are therefore available in a wide variety of colors and gloss levels. While smooth and even to the naked eye, decorative coatings can be porous on a microscopic scale and may not provide optimal corrosion protection. In outdoor applications requiring a decorative finish, excellent corrosion resistance can be achieved by using a two-coat primer/top-coat finish, or even a three coat primer/top-coat/clear-coat finish.
