  • Patent number: 6134863
    Abstract: There is provided a process of packaging metal pigment in a substantially non-dusting manner. The process includes the step of dampening the metal pigment with a liquid which may be water or an organic solvent compatible with that pigment type. The dampened pigment is then placed into a porous container which is sealed prior to removal of the liquid. The porosity of the container is chosen to permit removal of the liquid (for example by evaporation and/or centrifugation) whilst retaining substantially all of the pigment. Suitable containers include paper bags (such as autoclave bags), woven fiber materials (optionally calendered or coated) and polymer materials. The substantially dry metal pigment can be conveniently stored or transported within the container and is in a convenient form to use in a powder coating process.
