While the powder coating process may have lower costs over time, it may be more cost effective for specific coating applications to use liquid coatings. Some considerations to keep in mind when choosing between thermosetting and thermoplastic coatings are the method of application and the intended application for the coating. This limitation exists because immersing the preheated pieces in thermosetting powder can cause excess dust to flow back through the accumulated and residual heat in the liquid bed. Since the cross-linking reaction causes permanent changes in the powder material, such events would lead to excessive waste of coating powder. The curing process allows thermoconjunctions to achieve harder coatings than thermoplastics, making them resistant to higher temperatures and exhibiting greater scratch resistance and sea.
Harbor Freight is a leading company for the supply of cheap tools and offers a Chicago Electric powder coating kit. In general, professional equipment is quite expensive compared to the household powder coating budget. If you are willing to spend most of $ 10,000 on an oven and infrastructure to support it, a professional-quality weapon delivers fully professional results in practice. This is an important point, because you can achieve perfectly acceptable results for a small part of the professional price with hobbyist quality powder coating systems. You need buildings in an area divided into zones for industrial purposes, because you work with powder coatings made from resins, curing agents, pigments and chemical additives. You must find approved locations before you can apply for the company license and license, as these applications require location and facility details.
The Eastwood Powder Coating Gun is the most popular pistol for new fabric coatings and works significantly better than the Harbor Freight Powder Coating Gun and the Craftsman Powder Coating Gun mentioned above. After purchasing the nozzle and curing furnace, it’s time to find the right powder powder coating equipment coating pigments and other related materials. Note that the pigment mixture is generally not practiced unless the pigments revolve around the colors black, white, gray and cream. So if your customer wants to acquire a custom shade, they have to buy and choose the right color for the job.
Other necessary materials are cleaning solvents, masking accessories to cover uncoated areas and paint removers. Compared to the liquid coating process, the powder coating can more easily produce thicker coatings and even, especially when using the fluidized litter method. Using the ESD method, it is also possible to achieve thin and uniform coatings, although not as thin as the coatings achieved by the liquid coating process.
The gun gives the powder a negative charge, which is then sprayed onto the rectified object by mechanical spraying or compressed air and then accelerated into the workpiece by powerful electrostatic charge. The type of mouthpiece used depends on the shape of the workpiece to be painted and the consistency of the paint. The object heats up and the powder melts into a uniform film and then cools down to a hard coating. It is also common to first heat the metal and then spray the powder on the hot substrate.
