Powder coated bicycle frames and parts. The powder coating process was invented around 1945 by Daniel Gustin and received US Patent 2538562 in 1945. [4] This process coats an object electrostatically and then cures it with heat, creating a finish harder and tougher than conventional paint.
Limiting coating area is crucial in some applications, such as printing. "Roll-to-roll" or "web-based" coating is the process of applying a thin film of functional material to a substrate on a roll, such as paper, fabric, film, foil, or sheet stock. This continuous process is highly efficient for producing large volumes of coated materials ...
PVD coatings have the ability to utilize virtually any type of inorganic and some organic coating materials on an equally diverse group of substrates and surfaces using a wide variety of finishes. PVD processes are often more environmentally friendly than traditional coating processes such as electroplating and painting.
The coating acts as a sacrificial layer when it comes in contact with another surface so that the base material underneath is protected and remains unharmed. [2] [3] Abradable Powder Coatings safely reduce operating clearances and friction to improve the efficiency of compressors, pumps, engines, blowers, etc.
A powder feed stock is injected into the gas stream, which accelerates the powder up to 800 m/s. The stream of hot gas and powder is directed towards the surface to be coated. The powder partially melts in the stream, and deposits upon the substrate. The resulting coating has low porosity and high bond strength. [1]
Electrostatic coating is a manufacturing process that employs charged particles to more efficiently paint a workpiece. Paint, in the form of either powdered particles or atomized liquid, is initially projected towards a conductive workpiece using normal spraying methods, and is then accelerated toward the work piece by a powerful electrostatic charge.
Powder coating on glass requires specialized equipment. The biggest challenge is getting the powder to adhere to the glass surface since there is no natural electrostatic attraction like there is with different metals. A clean glass subsurface that will not interfere with the process is essential before beginning the powder coating procedure. [3]
Electrophoretic Deposition Process. Electrophoretic deposition (EPD), is a term for a broad range of industrial processes which includes electrocoating, cathodic electrodeposition, anodic electrodeposition, and electrophoretic coating, or electrophoretic painting.
