| Property: |
| Brown liquid; an anionic surfactant, resistant to acids, alkalis, salts etc, can well protect the colloid, no foams. |
| Use: |
(1)Can greatly improve the stability of system, the most effective diffusant in emulsion polymerization. It is used in the manufacture of styrene-butadiene rubber.
(2)As softening agent of reducing dyestuff, levelling agent in textiles dyeing, and high-efficiency water reducing agent of concrete. |
| Packing & storage: |
| In 200L steel drum, in room temperature and dry place, avoid collision and leakage, useful life is one year. |
