Study On Developments Of Processes For Powder Coatings, Shan Gao
Electronic Thesis and Dissertation Repository
Powder coating, which utilizes polymer resin based powder, is a relatively young technology for decorative and protective purposes. It was first developed in the early 1950s and gradually grew into automotive finishes. Compared to conventional liquid coating, powder coating is an environmentally friendly technology, given that there is no emission of harmful solvent throughout the entire operating process. It is also much more efficient, economical and energy saving as a result of the capability to reuse all the powder. However, there are still some problems in the powder coating process limiting its application. This thesis focused on studying some key …

Enamelled wire is a conductive wire coated with a very thin layer of insulation, widely used in the field that requires tight coils of wire. The traditional enamelled wire is produced by liquid paint, which consists of resins, solvents, pigments, and additives. Organic solvent takes a relatively high content, normally of 75% to 90% by weight. Many efforts have been made to decrease the percentage of solvent in the insulation paint. On the other hand, increasing the solids content of given enamel results in the viscosity rises significantly, making it harder to flow. Therefore, powder coating technology as an alternative …
