ABSTRACT:
Fibrous water-wet nitrocellulose containing 4.5 to 5.5% moisture sprayed with a solvent/cosolvent mixture converts to spheroid, densified nitrocellulose via bilateral agitation. A free-flowing dust-free product having a lower burn rate is produced which dissolves more rapidly for lacquer production. A preferred apparatus is an orbital shaker and a preferred solvent/cosolvent is isopropyl acetate/isopropyl alcohol.
