Process for applying polymer particles on substrate and coatings resulting therefrom

摘要

A heated substrate is dipped into a fluidized bed containing particles of polymer to coat the substrate. The coating can subsequently be leveled (and cured if thermosetting) by heating the coated substrate above the melting point of the polymer. The process can be employed to provide desirable properties such as corrosion resistance and aesthetic qualities to the substrate, and to apply very thin coatings.
