What Is Powder Coating?
Have you ever wondered how outdoor furniture sets always seem brand new, with no scratches or chips? That’s because most of these sets are powder coated to protect the metal beneath from harsh weather conditions over time.
Powder coating is a popular dry-finishing process known for its durability. Dry finishing involves attaching a powder to metal using an electrostatic spray gun. When enough static charge is generated between the medium and the workpiece, the fine-ground particles are attached to the metal’s surface. Once coated, the metal is baked in an oven, melting the power and forming a smooth, hard finish.
What Are The Benefits Of Powder Coating?
Powder coating is one of the most economical and longest-lasting finishes for metal surfaces with a significant advantage being its ability to produce thicker coatings than traditional liquid coatings. Powder-coated surfaces are highly resistant to damage like scratches, corrosion, chipping, and fading, making them ideal for applications in harsh environments. Powder coatings can last up to 40 years, once again depending on the environment and use. Manhole covers, for example, commonly have salt, sand, UV exposure, and traffic, which may reduce the life of the coating. Unlike rust-preventative paint, powder coating provides long-lasting color and does not require frequent touch-ups. This makes it a preferred choice for automotive parts, outdoor furniture, and especially manhole covers!
What Colors Are Available?
Many people assume that powder coatings only come in neutral colors, like your white refrigerator or black outdoor furniture, yet they actually come in a variety of colors and hues. Powders can be flat, satin, and gloss, as well as metallic and pearl. They also come in multiple textures, like hammerstone and river.
Overall, powder coating is a superior finishing process that provides a thick, uniform coating and resistance to corrosion or damage, making it an excellent choice for a wide range of metal applications.
