Characterization Of Fine Powders And Development Of Processes For Powder Coatings, Jing Fu

Electronic Thesis and Dissertation Repository

Traditional powder coating provides poor coating appearance. Fine powder coating can overcome this drawback since the smaller powder particles lead to much smoother finish. Nevertheless, fine powder has been experienced to cause more application problems. This study investigated fine powder coatings from different aspects and it provided solutions to solve these application problems.

The investigation on fine powders conducted by this study concluded that the medium particle size and D₁₀ was not suitable for the flowability characterization of fine powder coatings. Instead, an index which represented the particle size distribution could correlate with the flowabilities of the fine powder …
