Powder coating is well-known for creating beautiful, durable finishes. It’s perfect for all kinds of applications, thanks to its many useful properties. However, not all types of powder coating are exactly the same; some are better for certain things than others. For example, polyester and epoxy powder coating have different strengths that make them well suited for different purposes.
You can expect between 1 and 3 years of solid UV resistance from a standard polyester powder coating, which means it’s a good choice for a variety of indoor and outdoor applications. Plus, UV protection isn’t the only reason to choose polyester powder coating for outdoor applications—it also offers excellent protection from rain, wind, and other damaging elements.
In addition to being practical, polyester powder coating is attractive. It comes in a vast array of colors and gloss levels, and is thus perfect for situations where aesthetics matter.
Though epoxy powder coating is able to withstand a range of very harsh conditions, it is not UV resistant on its own. It can chalk, fade, and begin to break down as a result of sun exposure. However, there are plenty of additives and coatings that can be used in conjunction with epoxy to make it suitable for outdoor applications. In fact, it is often used as a primer—applied beneath a different coating—to provide strength and corrosion resistance without incurring sun damage.

Polyester Powder Coating
Polyester powder coating is the most common of the powder coatings—and for good reason. It provides excellent impact resistance and flexibility; good mechanical resistance; and good chemical resistance. It also has a low curing temperature, and is therefore suitable for sensitive components.You can expect between 1 and 3 years of solid UV resistance from a standard polyester powder coating, which means it’s a good choice for a variety of indoor and outdoor applications.

Epoxy Powder Coating
Epoxy powder coatings were some of the first to be commonly used. They offer many benefits, including excellent durability and hardness. Of the many available types of powder coating, epoxy is among the best in terms of corrosion resistance and chemical resistance. It also adheres well to metals, especially after pretreatments like sandblasting and phosphate coating.Though epoxy powder coating is able to withstand a range of very harsh conditions, it is not UV resistant on its own.
