What is powder coating?
The powder coating process uses a solvent free dry mix of plastic resins, pigments and fillers that melt and fuse together when heated. The solid particles of coating are electrostatically charged in a spray gun and carried by low velocity air to the surface of the piece to be coated. The electrostatic charge holds the powder particles in place while the part is cured in a 400-degree oven. The heat of the oven causes a chemical reaction to occur and the powder to cure, creating a highly durable finish.
It looks like paint but it acts like armor, states the Powder Coating Institute (PCI) of this ubiquitous surfacing technique. Powder coating is a highly durable, decorative and long lasting finish applied to products of nearly every sort for the consumer and industry alike. It can come in virtually any color or finish, matte or smooth, is rust-free, scratch resistant and ecologically friendly. Outdoor barbeques, swing sets, patio furniture and garden equipment are just a few examples of products that are powder coated. Though it appears painted on, it’s actually a dry finishing process. Electrostatically charged particles of pulverized pigment and resin are sprayed on to the surfaces of items that have been electrically grounded, thereby attracting the dry charged particles. Items are then placed in a curing oven where the powder coating melts and fuses to the surface. Not only is the process virtually pollution free, but there is also very little waste as the dry overspray can be reco
Powder coating is the process of coating a surface in which a powder material is applied using an electrostatic or compressed air method, or sometimes a fluidized bed. The applied powder is then heated (cured) in an oven to its melting point, after which it flows to form a smooth film which dries to a firm, durable finish very resistent to scratches, cracking, peeling, UV rays and rust. The entire powder coating process involves several steps.
Powder Coating is a method of using an electrostatic charge to apply a coating of resin and pigment powders to a surface. Due to the electrostatic attraction, the part holds a consistent volume of powder to its surface which in the end creates a high quality coating that is uniform and durable, as well as being free of the runs, drips, and sags that conventional wet coatings can manifest.
