Polynaphthalene Sulfonate Water Reducer Supplier Product Description:
JF SODIUM NAPHTHALENE SULFONATE POWDER (SNF-A)
(Synonyms: Sodium salt of Sulfonated Naphthalene formaldehyde poly condensate in powder form)
It is a high range water reducer, high concentration naphthalene-based superplasticizer, also named Naphthalene Sulfonate Formaldehyde Condensate (NSF), SNF, PNS and FDN etc. Na2SO4 less 5% contains no chloride, non-corrosive to steel bars, non-poisonous, odorless, and non-flammable. Thus, it meets the requirements of chemical admixture specifications for concrete: comply with ASTM C 494, Type F. ASTM C 1017, GB8076-2008 and GB50119-2003 etc.

Polynaphthalene Sulfonate Superplasticizer Application:
1. Reduce 10 to 25 percent of cement content when the strength and the slump of the concrete are basically same.
2. When the water cement ratio is constant, it improves the initial slump of the concrete by more than 10cm, and the water-reducing ratio can reach 15 to 25 percent.
3. Has remarkable early strength and strengthening effects on the concrete, and improve the strength by 20 to 60 percent.
4. Improve the workability of the concrete and comprehensively improve the physical and chemical properties of the concrete.
5. Adapt to various cements well, and is well compatible with other types of 0s.
6. Particularly applicable to the following concrete projects: flowing concrete, plasticized concrete, steam-cured concrete, impermeable concrete, waterproof concrete, naturally-cured precast member concrete, reinforcing steel bars and prestressed reinforced concrete, high-strength and ultra-high-strength concrete.
Polynaphthalene Sulfonate Usage:
Polynaphthalene Sulfonate is a thinner, used in the papermaking industry to control the pulp, reduce the two-sidedness, improve the retention of fillers or fine fibers, improve sizing, and reduce coating viscosity. Used as a high-efficiency dispersant for water-based paints and pigment pastes. Used as a colorant dispersant in acrylic series, aldehyde-acrylic series, and chlorinated latex paints. It can also be used as an adhesive, polymer filler powder and sealing layer to improve water resistance.
Polynaphthalene Sulfonate Superplasticizer Usage:
A. Blending dosage at 0.5%-1.0%, 0.6% mixing dosage advised.
B. Prepare solutions as required.
C. Direct use of powder agent is allowed. Alternatively the addition of the agent is followed by water moisturization (water-cement ratio:60%).
