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. 
 

Key Properties:

1. High Range Water Reduction: SNF can significantly reduce the water content of concrete while maintaining its workability, leading to higher strength and durability.
2. Sodium Sulfate Content: Available in different grades based on Na2SO4 content for various markets:
   • Export grades: 5%, 10%, 18%
   • Domestic grades: 3%, 23%
3. Chloride-Free: Contains no chlorides, making it non-corrosive to steel reinforcement in concrete structures.
4. Non-Toxic and Safe: It is non-poisonous, odorless, and non-flammable, ensuring safe handling and use.

Applications:

• Concrete Industry: Widely used in the production of high-performance concrete, precast concrete, and ready-mix concrete to enhance workability, reduce water content, and improve overall strength.
• Cement Products: Utilized in various cement products to achieve desired performance characteristics.
