![]() The surface texture which is considered desirable or acceptable depends on the end product. For such powder coatings, film build-ups of greater than 50 μm may be required to obtain an acceptably smooth film. Most powder coatings have a particle size in the range of 2 to 50 μm, a softening temperature Tg around 80 ☌, a melting temperature around 150 ☌, and are cured at around 200 ☌ for a minimum of 10 minutes to 15 minutes (exact temperatures and times may depend on the thickness of the item being coated). As the film thickness is reduced, the film becomes more and more orange peeled in texture due to the particle size and glass transition temperature (Tg) of the powder. While it is relatively easy to apply thick coatings that cure to smooth, texture-free coating, it is not as easy to apply smooth thin films. Finally, several powder colors can be applied before curing them all together, allowing color blending and bleed special effects in a single layer. ![]() Because no carrier fluid evaporates away, the coating process emits few volatile organic compounds (VOC). The process is useful for coatings on metal used in many household appliances, aluminum products and automotive parts.īecause powder coating does not have a liquid carrier, it can produce thicker coatings than conventional liquid coatings without running or sagging, and powder coating produces minimal appearance differences between horizontally coated surfaces and vertically coated surfaces. The finish is harder and tougher than conventional paint. This process puts a coating on an item electrostatically, which is then cured by heat. The powder coating process was invented around 1945 by Daniel Gustin and received US Patent 2538562 in 1945. Advancements in powder coating technology like UV curable powder coatings allow for other materials such as plastics, composites, carbon fiber, and MDF ( medium-density fibreboard) to be powder coated due to the minimum heat and oven dwell time required to process these components. Powder coating is mainly used for coating of metals, such as household appliances, aluminium extrusions, drum hardware, automobiles, and bicycle frames. It is usually used to create a hard finish that is tougher than conventional paint. The powder may be a thermoplastic or a thermoset polymer. Unlike conventional liquid paint which is delivered via an evaporating solvent, powder coating is typically applied electrostatically and then cured under heat or with ultraviolet light. Powder coating is a type of coating that is applied as a free-flowing, dry powder. ![]() Also to make washing your car even more convenient, we offer you a scratch-free car wash with microfiber cord gloves that are perfect for cleaning, dusting and polishing.Heat-sensitive carbon fiber tubes coated with a UV curable powder coating.
