<p>Manufacturing gel free nitrocellulose lacquers in shorter time by less hazardous methods is disclosed. A low boiling solvent, miscible with polyol polymer and nitrate ester, is used during the manufacture to provide a lacquer premix comprising the polyol polymerand nitrocellulose. The premix may be a clear solution or an emulsion. Explosive nitrate esters are added to the lacquer premix and the resulting admixture sparged to reduce the water (if present) and low boiling solvent each to beiow about 0.02% by weight and form the gel free nitrocellulose lacquer.</p> |
