For small-scale jobs, "rattle can" spray paint is less expensive and complex than powder coating. At the professional scale, the capital expense and time required for a powder coat gun, booth and oven are similar to those for a spray gun system. Powder coatings do have a major advantage in that the overspray can be recycled.
Gema Switzerland GmbH is a leading supplier in the area of electrostatic powder coating with a worldwide presence. From simple hand coating through to fully automated powder coating, this Swiss company offers solutions that meet the high demands and requirements of customers around the world in a wide range of industrial sectors.
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.
[citation needed] Many different mixtures of coating powders and D-gun settings can be used during detonation gun spraying of a material, all of which influence the final surface characteristics of the sprayed coating. Common powder materials used include but are not limited to: alumina-titania, alumina, tungsten carbide-tungsten-chromium ...

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]
Spray guns are aligned above the material and the guns are in motion to hit all the grooves of the material. The guns can be moved in a cycle, circle, or can be moved back and forth to apply the paint evenly across the material. Flatline systems are typically large and can paint doors, kitchen cabinets, and other plastic or wooden products.
