Customer Reviews
Received the sample from your company, which is very suitable for the concrete additives required by our factory, so we ordered a large number of products, it is a pleasant cooperation!

—— John Simmers

This is an old partner of our company! I've been ordering water reducer here for a long time, it's a trusted company, the ingredients are pure, and the product specifications I need are met.

—— Yogananda Muthaiah

The product content is high,the price is reasonable,already put into use,the cooperation is happy.


Many thanks to the workers who handled the packing of the pce liquid and lignin ,and to you of course. Packed very well.We have started work!

Chemical Concrete Admixture SNF Powder


PNS Sulfonated Naphthalene Formaldehyde

Product Description:

The full name of SNF is Sodium Naphthalene Sulfonate Formaldehyde Condensate. With high purity, SNF can enhance cement's dispersancy, reduce foaming, and achieve a higher range of water reducing.

The adoption of SNF can accelerate the project mould turning-over and construction speed, and help save cement at the same time. Additionally, SNF can also improve cement’s mobility and workability. To sum up, SNF is a high-range concrete admixture which is applicable to cast-in-place, prefabricating, pump and curing.

The product has a high water reduction rate of 15-30% and can significantly increase the strength of concrete at various ages.
Adding this product with the same construction conditions and design strength can save 10-20% of cement.
It has good adaptability to Portland cement, ordinary Portland cement, slag Portland cement and fly ash Portland cement.
It can significantly improve the durability of concrete impermeability and antifreeze.
low alkali content, per cubic meter of concrete (the amount of cement is 400KG), the alkali content (combined Na2O) increased by adding this agent is less than 1KG.
In accordance with the use of aliphatic water reducing agent and sulfamate water reducing agent, the effect and plasticity of the product are obviously improved.

SULPHONATED NAPHTHALENE FORMALDEHYDE (SNF) is an ideal material for use in building projects due to its remarkable adaptability to various cements, non erodent properties to reinforcing bars, and nonpoisonous and pollution-free nature. Furthermore, its applications in the field of construction have been vast and incorporates use in projects ranging from highways, bridges, tunnels, water conservancy hydroelectric projects, ports, quays, skyscrapers, power engineering, industrial civil buildings, and prestressing force components to even high range concrete.


SNF / PNS / FDN / NSF Sulfonated Naphthalene Formaldehyde Construction Chemical Concrete Admixture 1


1, this product is non-toxic, non-flammable, stable in shape, and has no rusting effect on steel bar.
2, the gas content is 2.0 ≤ 4.0%, which is beneficial to pumping construction.
3, the content of NF ≤ AIII sodium sulfate is less than 18%, and the alkali content is low, which will not cause alkali aggregate reaction.
4. standard superplasticizer: the water reducing rate is 14 ≤ 25%, the flowability of the mixture can be increased, and the slump of concrete can reach 15 ≤ 22 cm; The 60min loss of retarding superplasticizer is less than 50mm, which can delay the setting time of concrete by 2 ≤ 15h. through the test, the content can be increased and the length can be extended, and the strength of concrete can be improved in the later stage. When required, it is put forward that it is suitable for the continuous pouring of mass coagulation soil in hot season, which can reduce the hydration and heat release, reduce the temperature stress of concrete and avoid the occurrence of temperature difference cracks. Early strength superplasticizer: improve the early strength of concrete, frost resistance and other properties.
5. It has a strong dispersion effect on cement, and obviously improves the mixture and ease of operation, so that the concrete mixture is easy to pour and vibrate.
6, save cement, when maintaining the same strength, can reduce the amount of cement by 10-20%.
7. Increase the compactness of concrete, reduce shrinkage and creep, improve the durability of concrete and prolong the service life of concrete.
