Abstract
A coating of synthetic resins, plastics, sheeting varnish, colophane-type resins and other substances is applied to the surface of the pellets. Specifically the application of the protective coating is preceded by the introduction of a protective fluid into the pores, e.g. heavy oil, pitch fine charcoal in suspension, fine mineral materials, in suspension, and other substances.
