Advanced hybrid systems for indoor applications are established to cure at a temperature level of 125-130 °C (257-266 °F) preferably for applications on medium density fiberboards (MDF); outdoor durable powders with triglycidyl isocyanurate (TGIC) as hardener can operate at a similar temperature level, whereas TGIC-free systems with β-hydroxy alkylamides as curing agents are limited to approx. Epoxy Prime. Many manufacturers prefer to have a certain degree of orange peel since it helps to hide metal defects that have occurred during manufacture, and the resulting coating is less prone to showing fingerprints. Common is the use of flow promoter where the active ingredient -a polyacrylate- is absorbed on silica as carrier or as masterbatch dispersed in a polyester resin as matrix. CST epoxy coated tanks using the OptiBond process are becoming the standard for epoxy durability, corrosion resistance, UV breakdown, and abrasion. Epoxy Powder Coating The selection of the method depends on the size and the material of the part to be powder coated, the type of impurities to be removed and the performance requirement of the finished product. The standard coating thickness is around 200 micron. The powder sticks and melts to the hot object. endstream endobj 19 0 obj <>stream This allows the primer to melt deep into the profiled metal surface and create a strong mechanical bond. So while powder coating is sometimes less expensive than epoxy coating, as the saying goes, "you get what you pay for". Some finishing requirements call for both UV durability and corrosion resistance, which depending upon the specification, can be mutually exclusive. Hardener Resin and hardener in powder form are applied over the steel and heated to a particular temperature. Recent additional processes have been developed that avoid the use of chromates, as these can be toxic to the environment. Parts made with a thinner-gauge material need to be burned off at a lower temperature to prevent the material from warping. These charged powder particles then adhere to the grounded substrate. Some of the most popular types of powder coating include: Epoxy Powder Coatings; Polyester Powder Coatings; Hybrid Powder Coatings. to improve their wear resistance. Once the melted coating is in this temperature window it is instantly cured when exposed to UV light. They come under the category of protective coatings in paints and coating nomenclature. There are very specialized operations where powder coatings of less than 30 micrometres or with a Tg below 40 °C are used in order to produce smooth thin films. Further heating is usually required to finish curing the coating. The type of nozzle used will depend on the shape of the workpiece to be painted and the consistency of the paint. Powder can also be applied using specifically adapted electrostatic discs. Some heat sensitive plastics and composites have low surface tensions and plasma treating can be necessary to improve powder adhesion. Plastic media blast equipment uses plastic abrasives that are sensitive to substrates such as aluminum, but still suitable for de-coating and surface finishing.
