SNF stands for Sodium Naphthalene Sulfonate Formaldehyde Condensate. It is known for its high purity, which makes powerful cement particles, enhancing the dispersion and dissolving rate, decreasing the foaming, increasing the water reduction and significantly strengthening the concrete. As a result, SNF helps in accelerating the mould turnover of a project, speed up the construction process, reduce the amount of cement used and improve the mobility and workability of cement.
SNF is a highly effective concrete admixture, suitable for cast-in-place, prefabricating, pump and curing concrete projects.

The amount of cement admixture should be 0.5-1.0%, which can help reduce the cement amount 20-30%. By mixing this product at a rate of 0.7% (solid content) of cementing materials, the slump can increase more than 10 cm, while keeping the concrete strength.
It is suitable for high strength concrete, early strength concrete, flowing concrete, prefabrication concrete, curing concrete and pre-stressed concrete. If the pilot development or laboratory experiment succeeds, this product can be combined with other externally applied agents.
Blending dosage at 0.5%-1.0%, 0.7% mixing dosage advised.
Prepare solutions as required.
Direct use of powder agent is allowed. Alternatively the addition of the agent is followed by water moisturization (water-cement ratio: 60%).
The agent can be combined with other externally applied agents if pilot development or laboratory experiment succeeds.
1) PNS used for and widely for self cured, vaporcured 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.
2)PNS suitable for preparation of early-strength, high-strength, high-anti-filtration and self-sealing& pumpable concrete.
3)PNS 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.
Sulfonated Naphthalene Formaldehyde (SNF) is typically packaged in 25 kg bags, 1000 kg bags, and bulk bags of up to 1,000 kg. It is shipped in drums, IBCs, or containers.
When packing SNF, it is important to ensure that the material is properly sealed and labeled. This includes using stretch wrap and corner boards to ensure that the packaging is secure and the material is protected from any potential damage during transport.
When shipping SNF, it is important to ensure that the container is properly sealed and labeled. This includes using appropriate shipping labels, indicating the contents of the container and the relevant safety information. It is also important to ensure that the material is not exposed to any extreme temperatures, as this could potentially affect the quality of the product.
