In many high end applications, the part is electrocoated following the pretreatment process, and subsequent to the powder coating application. Curing[edit]. The gun imparts a positive electric charge to the powder, which is then sprayed towards the grounded object by mechanical or compressed air spraying and then accelerated toward the workpiece by the powerful electrostatic charge. In 2010, the global demand for powder coatings amounts to approximately US$5.8 billion. ^ DSM Coating Resins (October 2004). Blasted then powder coated (before and after) . The thermosetting variety incorporates a cross-linker into the formulation. Plastic media blast equipment uses plastic abrasives that are sensitive to substrates such as aluminum, but still suitable for de-coating and surface finishing. When a thermoset powder is exposed to elevated temperature, it begins to melt, flows out, and then chemically reacts to form a higher molecular weight polymer in a network-like structure.

The pre-treatment process both cleans and improves bonding of the powder to the metal. A coating method for flat materials that applies powder with a roller, enabling relatively high speeds and accurate layer thickness between 5 and 100 micrometres. Most powder coatings have a particle size in the range of 30 to 50 (Microns), a softening temperature Tg around 80C, a melting temperature around 150C, and are cured at around 200C. Production:. Powder application processes[edit]. Types of powder coating[edit].


The wide range of speciality effects are easily accomplished using powder coatings that would be impossible to achieve with other coating processes.[2] . It is also common to heat the metal first and then spray the powder onto the hot substrate. This method of preparation is highly efficient on steel parts such as I-beams, angles, pipes, tubes and large fabricated pieces. Market[edit].

The object is then heated, and the powder melts into a uniform film, and is then cooled to form a hard coating.


^ "Market Report: Global Powder Coating Market". Methylene chloride and acetone are generally effective at removing powder coating, however most other organic solvents (thinners, etc.) are completely ineffective. The powder sticks and melts to the hot object. At the professional scale, the capital expense and time required for a powder coat gun, booth and oven are similar to a spray gun system. The curing schedule could vary according to the manufacturer's specifications. The online consumer market typically offers media blasting services coupled with their coating services at additional costs. The type of nozzle used will depend on the shape of the workpiece to be painted and the consistency of the paint. The thermoplastic variety does not undergo any additional actions during the baking process, but rather only flows out into the final coating. See also[edit].
