Powder coatings are 100 percent solid material and are free from solvents. The electrostatic powder coating process is a method of applying electrically – charged powder material, to grounded parts. The powder is held to the part by this electrostatic attraction until heat is added by use of a powder coating oven to flow the powder together and cure it. (The electrostatic attraction is similar to the static in your dryer).
When powder coating was first used in the 1950’s in North America, the powder system was limited in terms of colors, thickness, exterior durability, and product applications. Powder coating began with the coating of pipe for corrosion protection and electric motors for insulation.
Powder’s advances have been fueled by increasingly stringent EPA regulations, escalating energy costs, increased consumer demands for product durability, and heightened awareness of powder and its benefits. In just a few short decades, powder has set a standard for durability and corrosion resistance which is difficult to match with competitive finishing systems. The selection of powder coating technology offers the finisher an alternative that is economical, efficient, environmentally desirable, produces a high quality finish and is available in a wide selection of decorative colors, glosses and finishes ( i.e. textures, wrinkles, smooth, rough, etc.).
