NITROCELLULOSE, SOLID
HERCULESE nc4000
RS 5.0-6.5 SEC, 12-12.3% N2

Nitrocellulose, Solid 12.0-12.3% Nitrogen   RS 5.0 to 6.5 sec Herculese 4000 series 25% water - [C6H7N3O11] Stock #C163/NCS - FS    Shipped as an ORM-D

Herculese NC4000 series, 12.0-12.3% nitrogen, used to manufacture single base, slower burning smokeless propellants and as a burn rate modifier to obtain a variety of propellants. Shipped moist according to regulations. You pay for the NC, not the water. Simply dry and dissolve in Acetone, n-butyl acetate or any solvent listed in the chart below to obtain a variety of viscosities and dry times. For 'lacquer', 1 to 1.75 oz NC/qt of Acetone for binder for stars, smoke (slow dry times are warranted for these applications), igniter pyrogens (fast dry times requires), etc.; 3.5oz/qt of Acetone for thick concentrate, or 5.25 oz to make high viscosity 16% solids lacquers. 1 lb makes up to approx 4 gallons of solution. Maximum absorption is approx 4.5 to 5.0 oz NC per quart for a jelly-like viscosity. Methanol can be added to both slow evaporation/gelling (extend work time) and lower the solution viscosity. Up to 10% methanol is common practice. The following chart depicts solvents and their corresponding evaporation rates that are uses as nitrocellulose solvents. Legend: Acetone evaporates faster than all; Note: the lacquer viscosity listed in the chart is based on 1/2 sec nitrocellulose found in almost all commercial NC lacquers, and not the RS 5.0-6.5 sec NC Firefox supplies. Remember, it takes over twice as much 1/4-1/2 sec NC to make the same viscosity lacquer when made using our 5.0-6.5 sec NC 4000 series! Formulation Example: the highest viscosity comes from using N-Butyl Acetate (highest molecular wt), but the downside is that it has the slowest evaporation rate thus taking the longest to dry. Therefore, a combination of acetone and ethyl acetate would yield the best properties and require less nitrocellulose to obtain the desired viscosity and dry time.
