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:
High Range Water Reduction: SNF can significantly reduce the water content of concrete while maintaining its workability, leading to higher strength and durability.
Sodium Sulfate Content: Available in different grades based on Na2SO4 content for various markets:
Export grades: 5%, 10%, 18%
Domestic grades: 3%, 23%
Chloride-Free: Contains no chlorides, making it non-corrosive to steel reinforcement in concrete structures.
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.
