Powder coatings are based on polymer resin systems, combined with curatives, pigments, leveling agents, flow modifiers, and other additives, process called electrostatic spray deposition (ESD) is typically used to achieve the application of the powder coating to a metal substrate. After application of the powder coating, the parts enter a curing oven where, with the addition of heat, the coating chemically reacts to produce long molecular chains, resulting in high cross-link density. These molecular chains are very resistant to breakdown. This type of application is the most common method of applying powders Sometimes a powder coating is applied during a fluidized bed application. Preheated shutter parts are dipped in a hopper of fluidizing powder and the coating melts, and flows out on the part. Post cure may be needed depending on the mass and temperature of the part and the type of powder used. No matter which application process is utilized, powder coating rolling shutter are best in terms of quality than that of G.I Rolling shutter, cost effective, and tough!
