Investigation into the various parameters affecting the application of thermosetting powders by electrostatic powder coating onto decorated tinplate and its ability to withstand tooling deformation without any noticeable breakdown

Abstract

The report is intended to provide a survey of electrostatic powder coating principle, the parameters involved and how it car. be used to give a protective and decorative thin surface film on printed tinplate, which would in turn withstand a tooling deformation. Phenomena associated with electrostatic powder coating are examined and the principle applications of the process to film production are described. In addition to an investigation of the conventional type process currently used in industry, new developments are discussed. The application is the hardware range components produced by (/up 10). Metal Box S.A. Limited, wi.-ch would compete favourably with plastic products, serving the same market because of a durable, corrosion resistant, scratch free sru*face. This survc. will form the grounding work for further investig- ation into different areas and processes for decorating tinplate. Assumptions and limitations of the work have been based on available local and overseas data and estimates of accuracy of numerical result.-, have been reccrdod as - b t .
