Application:
| Grades | Application | |
|---|---|---|
| 1 |
|
Lacquers for wood and paper where the highest solid content is desired. |
| 2 |
|
Lacquers for wood and paper where the higher solid content is desired. More versatile and durable than SS 1/8". |
| 3 |
|
Its purpose is similar to SS 1/4", but SS 1/2" and SS 1" are slightly more durable. |
| 4 |
|
Its application is similar to the SS 1/2" and SS 1", yet more durance and higher viscosity. |
Remark:
1. Nitrocellulose is not soluble in water, but isopropanol is miscibled.
2. Nitrocellulose is soluble in esters, ketones, glycol-ether and alcohol mixtures.
3. Nitrocellulose is compatible with other resins, and it must be checked before use.
4. NC Samples are available upon formal request (1kg of sample in PVC container for each specification).
5. Handling precautions：
Always attach grounding wire to the complete packaging system (fiber drum and anti-static polyethylene liner) before emptying fiber drums.
6. The information provided herein is for general introduction.
7. Users are required to confirm the suitable formulation, process and evaluation for consistency of quality control.
