ral/pantone powder coating:we could custom colors by ral/pantone number.
Hsinda powder coatings provide superior powder coating protection for your metal products needs. Powder coated surfaces on metal surface offer greater resistance to scratching, fading, chipping and scarring and wear better than other finishes.
Powder coating also offers a variety of aesthetic benefits such as many different colors and textures for your custom metal powder coating specifications.
Powder coating has become tremendously popular in the metal industry, especially in metal furniture and shelf,appliance,car. The process has now completely overtaken the metal products market due to its affordability, durability, decorative and eco-friendly properties.
Powder coating has the advantages of no pollution, no solvent, achieving a perfect thick layer by spraying just one time and recycling the overspray powder. Because of the limit of strengthening VOC in the world which has prompted this new ecofriendly material to develop. Compared with the traditional solvent paint, what are the Specific advantages of powder coating?

How Powder Coating Works
Powder coatings are based on polymer resin systems, combined with curatives, pigments, leveling agents, flow modifiers, and other additives. These ingredients are melt 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 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. Powder coatings can also be applied to non-metallic substrates such as plastics and medium density fiberboard (MDF).
Sometimes a powder coating is applied during a fluidized bed application. Preheated 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 coatings are easy to use, environmentally friendly, cost effective, and tough!
