Abstract: A process for producing compacted free-flowing nitrocellulose based lacquer raw materials is described. The process involves pressing a nitrocellulose based lacquer feed material, which is moistened with alcohol or water, through the holes of a die. The pressing step may be performed by means of at least one circulating breaker. The process optionally comprises shearing off the compacted lacquer raw material into pieces of selected length, below the die. The compacted nitrocellulose based lacquer raw materials prepared by the process of the present invention are free flowing and have a moisture content of at least 25%.
