Sodium Naphthalene Sulphonate

Naphthalene formaldehyde sulphonate water reducing agent is a synthetic powder based onbeta-sulphonate formaldehyde ondensate and reactive polymer.
It has the properties of high range water reduction, set retarding and excellent strengthening.
Elt-nsf sodium sulfate is less than 10% , suitable to middle strength or high strength concrete where high range water reduction is desired.


A. Used for and widely for self-cured, vapor-cured concrete and its formulations. At the early stage of application, 

     extremely prominent effects are shown. As the result, the modulus and site utilization can be drastically, the 

     procedure of vapor cure is omitted in peak-heat summer days. Statistically 40-60 metric tons of coal will be 

     preserved when a metric ton of the material is consumed.
B.Suitable for preparation of early-strength, high-strength, high-anti-filtration and self-sealing& pumpable concrete.
C.Widely used in pre-cast & ready-mixed concrete, armored concrete and pre-stressed reinforced concrete in key  

    construction projects such as dam and port construction, road building & town planning projects and dwelling 

    erections etc.

D.Compatible with Portland cement, normal Portland cement, Portland slag cement, fly-ash cement and Portland 

    pozzolanic cement etc.
