Sodium Naphthalene Sulfonate

Sodium naphthalene sulfonate (Sodium Naphthalenesulfonate Formaldehyde, SNF) is an anionic surfactant available as a brown liquid. It is used as a water-reducing agent in concrete admixture formulations. SNF is commonly used to prepare free-flowing and pumpable concrete mixes. Improves concrete cohesion by reducing segregation and bleeding, and provides high slump retention performance without affecting setting time.
