Name: Short for SNF, PNS, FDN
Also called: Poly Sodium Naphthalene Sulphonate;
The product is made of naphthalene, sulfonic acid, HCHO and Alkali
through sulfonation, condensation, hydrolyzation, and
Naphthalene formaldehyde sulphonate water reducing agent is a
synthetic powder based on
beta-sulphonate formaldehyde ondensate and reactive
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.
We have 3 models: SNF-A; SNF-B; SNF-C.

Technical features & adaptability:
1. Mixing amount: 0.5-1.0% of cementing materials, reducing rate:
2. Keeping concrete strength intact & mixing this product,
cement saving amount can reach 15-20%
3. Mixing this product 0.7% (solid content), slump constant
increases above 10cm
4. Adapting to high strength, early strength, flowing,
prefabricating & curing and prestressing force concretes etc.
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
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 &
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.
A. Blending dosage at 0.5%-1.0%, 0.6% mixing dosage advised.
B. Prepare solutions as required.
C. Direct use of powder agent is allowed. Alternatively the
addition of the agent is followed by water moisturization
