Abstract

Traditionally, silver, gold or other metallic finish powder coatings have always presented problems. Originally, the process used involved dry blending bronze or aluminium flakes with the resin powder. However, the different Specific Gravities of the two constituents caused separation problems, as well as proving expensive, as the powder could not be reclaimed and used again. There is also the danger of loose aluminium in the atmosphere.
