Description

Sodium Polynaphthalene Sulfonate is a naphthalene-based highly effective water reducing agent for promoting accelerated early and ultimate strength development, commonly referred to as a superplasticizer, also named Naphthalene Sulfonate Formaldehyde Condensate (NSF), SNF, PNS and FDN etc. Sodium Polynaphthalene Sulfonate also known as SNF Superplasticizer, naphthalene-based superplasticizer, is a widely used admixture in the construction industry. It is primarily composed of β-naphthyl sulfonate formaldehyde condensates, which makes it an effective dispersing agent and high-range water reducer. The main ingredient of SNF is β-naphthalene sulfonate formaldehyde condensates, which is a non-air-entraining agent. It is available in powder form and has good adaptability to various cements, enabling it to improve the operability of concrete.

Application

Produces the high slump flowing concrete with no loss in strength.Produces low water/cement ratio concrete with high strengths.

Ideal for using in high strength concrete, flowing concrete, early strength concrete, precast steam curing concrete, prestressed concrete etc. where it is desired to keep the water/cement ratio to a minimum and still achieve the degree of workability necessary to provide easy placement and consolidation.

Be used as basic material to produce others compound admixtures, (such as accelerating and water-reducing admixture, retarding and water-reducing admixture, pumping antifreeze and pumping water-reducing admixture, etc.) 

Advantages

a).Exceptional Water Reduction

Reduces water demand by up to 25%, enabling low water-to-cement (w/c) ratios for higher compressive strength and long-term durability.Minimizes shrinkage and cracking in hardened concrete.

b).Enhanced Workability Flow

Improves slump retention and pumpability, even in high-temperature or high-shear conditions.Ideal for dense reinforcement structures, precast elements, and self-compacting concrete (SCC).

c).Accelerated Strength Development

Boosts early and ultimate strength gains, reducing curing times and accelerating project timelines.

d).Cost Efficiency

Lowers cement consumption while maintaining performance, cutting material costs and carbon footprint. Reduces labor and energy costs through easier placement and finishing.

e).Compatibility & Stability

Compatible with all cement types (OPC, PPC, slag, fly ash) and other admixtures. Resists segregation and bleeding, ensuring uniform concrete quality.
