Powder coatings can be applied to used parts only after they’ve been decreased and chemically cleaned to provide a proper surface for the electrostatically paint coating being applied. The part is then placed in an oven for two to four hours to complete the coating process. Typical cure temperatures for powder coatings are between 350 degrees Fahrenheit and 425 degrees Fahrenheit.
Ceramic coating: Dip-Spin
Ceramic coatings, on the other hand, come in two applications. These include dip-spin and traditional wet spray applications. Dip-spin is used most often with large quantities of small to medium-sized parts. The parts are surface-prepared and placed in a bin with perforated sides and bottom. The bin then gets dipped in another larger bin containing the liquid ceramic coating, lifted out of the larger bin, and spun to get the excess coating off the parts. This lowers the waste of the coating, and it allows large quantities of parts to be evenly coating at a single time. Once the process is complete, the parts are run through a large oven to fully cure the coating.
Ceramic coating: Traditional Spray
The more traditional “wet spray” ceramic coating process is used on larger parts. These coatings can be used for a large variety of parts. The only requirement is that they can withstand temperatures of 750 degrees Fahrenheit for three to five hours. That’s where high-temperature ceramic coatings come in. Ceramic is incredibly heat resistant, and it can withstand temperatures of 3,800 degrees Fahrenheit (2,000 degrees Celsius). After the surface preparation is complete, the high temp coatings are sprayed on the part and placed in a large oven for curing; the oven style is very similar to that used in the dip-spin process.
If you’re looking for a coating that is chip, heat, and corrosion resistant, then the ceramic coating is the way to go. Ceramic coating provides a thermal and corrosion barrier that reduces heat for extended life of your equipment.
