Naphthalene Sulfonate Formaldehyde Condensate (SNF), also known as Poly Naphthalene Sulfonate (PNS) and Formaldehyde Sulfonate Condensate (FDN), is a highly effective water reducer and superplasticizer commonly used in the construction industry to improve the workability and strength of concrete.
Features:
1,Main ingredient is β-naphthyl sulfonate formaldehyde condensate, sodium sulfate ≤5 and 10 and 18 and 23%. 4 main types.
2,Good dispersion, water reduction and early-strength effect. It can speed up the turnover of templates and fields, accelerate construction progress and shorten the completion period. It is applicable for concrete with early-strength and high-performance requirements and other concretes that need to enhance strength and improve long term performance.
3,Increase the concrete slump and improve its liquidity, applicable for ready-mixed concrete, pumping concrete, high-liquidity concrete, grouting material, etc.
4,Without air entraining. It is applicable for all grades of concrete with steam curing condition and natural maintenance.
5,No corrosion on steel bars. It is applicable for precast concrete, cast-in-place concrete, reinforced concrete, prestressed reinforced concrete, etc. in various projects.
6,Good compatibility with portland cement, regular portland cement, portland slag cement, portland flyash cement, etc.FDN-05 has good compatibility with portland cement, regular portland cement, portland slag cement, portland flyash cement, etc.II. Main Indexes of Performance and Quality.

1. Application Method and Notice:
1,Blend dosage range is 0.5-1.2%. Appropriate blend dosage can be selected according to project object and the materials used during application.
2,FDN powder is recommended to be applied in solution. It can be used in dry form, but make sure mix it thoroughly with concrete.
3,If this product is applied with adoption of stagnant water blending method or post-blend approach, water reduction and dispersion will be better.
4,This product can be formulated with concrete additives of other varieties. It can be "double blended" with blending materials such as fly ash, ground slag, etc. But the blend dosage shall be calculated based on the total of cementing materials.
5,When this product is used for the first time or cement variety is changed, concrete trial preparation shall be conducted according to the adopted materials and construction requirements in the field. Construction mixing rate shall be adjusted based on testing result to serve as instruction for construction blending.
1.Suitable for long-distance construction projects type pumping concrete.
2.Suitable for compounding normal concrete,high-performance concrete,high-strength concrete and ultra-high strength concrete.
3.Suitable for impervious,antifreezed and high durability concrete.
