100% Original China Poly Naphthalene Sulfonate …

Product Details: Sodium Naphthalene Sulphonate Formaldehyde Condensate is the sodium salt of naphthalene sulfonate polymerized with formaldehyde, also known as sodium naphthalene formaldehyde (SNF), poly naphthalene sulfonate formaldehyde (PNS), or naphthalene sulphonate formaldehyde (NSF). It is a chemical synthesis of a non-air-entraining superplasticizer with strong dispersibility on cement particles, producing concrete with high early and ultimate strength. It is widely used as a high-range water-reducing admixture in prestress, precast, bridge, and deck concrete to minimize the water/cement ratio while maintaining workability. The recommended dosage is 0.75-1.5% by weight of cement.

Pros:

Sodium Naphthalene Sulfonate Formaldehyde …

Product Details: Sodium Naphthalene Sulphonate Formaldehyde is a high-range water-reducing admixture. It produces concrete with extremely workable characteristics, referred to as high slump, and allows concrete to be produced with very low water/cement ratios at low or normal slumps. It is ideal for use in prestress, precast, bridge deck, or any concrete where it is desired to keep the water/cement ratio to a minimum and still achieve the necessary workability for easy placement and consolidation.
