Fdn Naphthalene Superplasticizer, Brand Name : JR for Concrete Mixing

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. 

It has good adaptability to various cements and improves the operability of concrete.FDN has the advantage of high water reducing ratio, non-delayed coagulation, non-air entraining and strong adaptability. It can improve the workability of concrete to a large extent so as to reduce the water consumption for blending. Meanwhile, it can improve the 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.
