Powder coatings are based on polymer resin systems, combined with curatives, pigments, levelling agents, flow modifiers, and other additives.  These ingredients are melted mixed, cooled, and ground into a uniform powder similar to baking flour.  A process called electrostatic spray deposition (ESD) is typically used to achieve the application of the powder coating to a metal substrate.  This application method uses a spray gun, which applies an electrostatic charge to the powder particles, which are then attracted to the grounded part.  After application of the powder coating, the parts enter a curing oven where, with the addition of heat, the coating chemically reacts. Powder coated items are very resistant to breakdown and harsh enviroments.  

 No matter which application process is utilized, powder coatings are easy to use, environmentally friendly, cost effective, and tough!
