Manufacturers apply electrostatic powder coating to many types of products
Manufacturers may apply an electrostatic powder coating to many types of products. This type of finish is primarily used on metals ranging from steel to aluminum. It’s also used to finish a variety of consumer goods, from wire shelving to lawn furniture. Electrostatic powder coating is also used on cars and other vehicles, and remains a popular method of finishing exterior metal siding.
This product may contain a variety of materials, depending on the product and manufacturer. Many include an epoxy resin base, though some rely on polyester-based hybrid mixtures instead. While polyester reduces the risk of yellowing on a powder coated finish, it also offers less corrosion resistance. Acrylic products are used to create a electrostatic powder coating with a high-gloss finish, while enamel-based versions are commonly used to finish electronic and mechanical equipment.
