Sodium naphthalene sulfonate formaldehyde (SNF) is light yellow to yellowish brown powder, which is an anionic surfactant. It is widely used for the preparation of free-flowing and pumpable concrete mixture. It is widely used in the construction industry. Sodium naphthalene sulfonate formaldehydecan be used as raw material for compound accelerators, anti-freezing agents, and retarders, in different construction industries. It is also known as dispersing agent NNO, diffusing agent NNO, sodium naphthalene-2-sulfonate formaldehyde, sodium polynaphthalene sulfonate, sodium naphthalene sulfonate formaldehyde concrete agent, etc. Its high purity feature makes cement particles with high low foaming, high range water reducing and strengthening. In addition, it also improves cement mobility and workability. Sodium naphthalene sulfonate formaldehyde is easily soluble in ethylene glycol, diethylene glycol, glycerol, and water, slightly soluble in alcohols, but it is insoluble in organic solvents.
