               Sodium Naphthalene Sulphonate

Sodium Naphthalene Sulphonate Formaldehyde (NSF) is a naphthalene-based superplasticizer, also named Sodium Naphthalene sulphonate Formaldehyde Condensate (SNF) and Poly Naphthalene Sulfonate (PNS), etc. It is a high range water reducer, commonly referred to as superplasticizer. It is a chloride free product that’s supplied as a brown powder to be instantly dissolved in water. It’s used to effect substantial water reduction to concrete without influencing normal setting time.

Sodium Naphthalene Sulphonate Formaldehyde (SNF/NSF /PNS) complies with the requirements of the following standards: ASTM C 494, Type F; ASTM C 1017.

It’s the most widely used concrete admixture at present and takes for 80% of total consumption. It’s extensively used in concrete mixing plants.

It’s used for making concrete below the strength grade of C60. When compounded with other admixtures, it’s applied in pumping concrete, curing concrete and others that have special requirements. Sodium Naphthalene Sulphonate is derivatives of sulfonic acid which contains a naphthalene functional unit.
