Herculese Nitrocellulose, Solid 12.3-12.5% Nitrogen, RS 5.0 to 6.5 sec 4000 series - [CH7N3O11]

Stock# C163/NCS

Price: $19/lb

ORDER

Shipped with 25% water according to regulations. You pay for the NC, not the water. Simply dry and dissolve in Acetone, or any of the other solvents listed in the chart below for lacquer; 1 to 1.75oz NC/qt of Acetone for binder for stars, smoke, igniters, etc.; 3.5oz/qt of Acetone for thicker concentrate. 1 lb makes up to approx 4 gallons of solution. Maximum absorption is approx 6.75 oz NC4000 per quart for high 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 used as nitrocellulose solvents. Legend: Acetone evaporates faster than all; Note, the lacquer viscosity listed is based on 1/2 sec nitrocellulose 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 (by weight) 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, as shown in our chart below, a combination of acetone and ethyl acetate would yield the best overall properties and require less nitrocellulose to obtain the desired viscosity and dry time. Note; substituting N-Butyl Acetate for Ethyl Acetate will increase the viscosity and dry time one more step.
