COMPOUND FOR PREPARATION OF PAINTS AND LACQUERS COMPOSITIONS OF NITROCELLULOSE GUNPOWDERS

摘要

The compositions are applied as colourless laquers, enamel lacquers, primers and mastics in the industry and the household. The solutions of the nitrocellulose gunpowders have dry content above 10% and viscosity suitable for the production of a great variety of compositions, primers and mastics. The time for the gunpowder dissolution is considerably reduced. The composition contains, in wt.%: nitrocellulose gunpowder from 2 to 18, nitrocellulose from 1 to 15, synthetic resins from 5 to 20, plastifiers from 1 to 10, pigments from 5 to 25, fillers from 5 to 50 and solvents - acetone in combination with one or more of the following solvents: methylisobutylketone, acetates and aromatic solvents and alcohols. The ratio of the acetone to the remaining solvents is from 5 to 20 to 30 to 85.
