An additional advantage for UV-cured powder coatings is that the overall process cycle, the cure application, is faster than other coating methods. If you are looking for “Energy Layer Benefits”, “Dust Layer Advantages” or “Dust Layer Awakens” then this post should help! The advanced powder coating method is used for protective and decorative finishes of any metal used by consumers and industry. The process uses a powder consisting of resin and fine pigment particles, electrostatically sprayed on the metal surface.
Because the powder coating does not allow the accumulation of small films, it is generally not possible to touch a part. With the powder coating you generally have to remove all original coating powder coating machine to achieve a quality finish. Liquid coating allows you to sand and prepare part of a product and achieve a mixed finish that is difficult to distinguish from the rest of the product.
All powder coatings must be baked in an oven, so environmental protection is not an option. Powder coating is one of the most popular finishing techniques currently available on the market and is becoming increasingly popular across the industry. The powder coating market grew by about 6 percent after 2010 and has made great technological progress. You develop new application processes and coating formulas to expand the width of applications where powder coating can be used. Among the wide range of applications and the incredible practical and financial benefits it offers, you will now find powder coating on all types of devices and everyday items.
By adding compressed air to dry powder to “fluidize” the material, he was able to spray the coating and supply a decorative film. The process was introduced in the United States in the 1960s and rapid growth continued over the next 30 years. Ultraviolet cured powder coatings have been in commercial use since the 1990s and were initially developed to finish heat-sensitive medium density fiberboard furniture components. This coating technology requires less thermal energy and heals significantly faster than thermally cured powder coatings. Typical residence times for UV curly powder coatings are 1 to 2 minutes with coating temperatures from 110 to 130 ° C.
Each phase is generally separated by a flush phase to eliminate the remaining chemistry. Spray systems allow pre-treatment of a wide variety of part sizes and configurations; Dip trays can be used for some applications instead of syringes. It is easy to see how powder coating outperforms traditional paint options in several areas. With the right equipment, you can shorten the end time, increase the quality of your finish and open up a wider range of finishing options.
As the powder coating processes have become more advanced and specialist, the width of the applications has only expanded to more corners of the manufacturing industry. In the automotive accessories market, high heat resistance powder coatings are used to finish silencers to resist corrosion, protect against notches and extend the life of the silencer. Light truck and SUV owners can purchase dust-fired stirrups, railings, luggage racks and tool boxes as accessories for the dealer or accessory market.
Since its introduction more than 40 years ago, powder coating has grown in popularity and is now used by many manufacturers of ordinary household and industrial products. In North America, it is estimated that more than 5,000 finalists apply powder to produce high-quality, durable finishes in a wide variety of products. Dust-coated finishes are resistant to scratches, corrosion, wear, chemicals and detergents, and the process can reduce costs, improve efficiency and facilitate compliance with environmental rules. Manual powder coating spray booths allow workers to manually prepare, coat, dry and heal batch items. They work well for an occasional dust coating project, but cannot keep up with large-scale production requirements.
Because no carrier fluid evaporates, the coating process emits few volatile organic compounds . Finally, different powder colors can be applied before they are all healed together, so you can mix color and bleed special effects in one layer. Among all else, powder coating is a very environmentally friendly way to color a metal part. Although applied by spray powder to the part, the powder does not contain hard chemicals designed to hold it.
