METHOD OF PREPARING VARNISHED COMPOSITION Russian patent published in 1999 - IPC

Abstract RU 2134706 C1

FIELD: paint and varnish industry. SUBSTANCE: method comprises mixing varnished colloxylin at elevated temperature and solvent, and subsequently adding plasticizer, diluent and additives. Varnished colloxylin is prepared by previously mixing highly viscous cellulose nitrate with solvent in the presence of catalyst. Varnished composition is prepared in one apparatus at 60-70 C under atmospheric pressure. Method makes it possible to use cellulose nitrates of any grades including pyroxylin powders without removing diphenyl amine from composition thereof. EFFECT: more efficient preparation method. 2 cl, 8 ex, 3 tbl
