What is powder coating? Powder coating is a dry finishing process that has steadily gained popularity in the industrial marketplace since its introduction in the 1960s. It provides a durable, high-quality coating to manufacturing equipment that offers superior protection and looks great.
The powder coating process begins with polymer-based dry powders that contain pigments, curatives, flow modifiers, leveling agents, and other additives. These are applied to the metal surface with an electrostatic spray gun that delivers a positive electric charge and then baked in a curing oven, resulting in a smooth coating with a hard finish.
Because powder coating has no liquid carrier, it allows matching of superior powder coating colors and produces a thicker coating. Powder coating can be applied to different types of metals including steel, copper, and aluminum. It is resistant to moisture, chemicals, ultraviolet light, scratches, chips, abrasions, corrosion, and fading.
How long does powder coating last? It can last as long as 20 years, making it one of the most economical, durable, attractive, and long-lasting quality finish available.
