Sodium Naphthalene Sulfonate / Concrete Admixture Naphthalene Sulfonate Formaldehyde NSF / SNF Superplasticizer

Product Description

1. Sodium naphthalene 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.
2. Sodium naphthalene sulfonate contains no chloride, non-corrosive to steel bars, non-poisonous, odorless, and non-flammable.

3. It is a chemically synathesized non-air-entrained superplasticizer .
4. Also called naphthalene sulfonate formaldehyde condensate .
5. Has strong dispersion effect on cement particles and good use effect of preparing super flowing concrete as well as cast-in-situ concrete .
6 . Precast members with early strength and high strength requirements
7. Comprehensively improve various properties of the concrete .


1. Substantial improvement in workability without increased water or the risk of segregation. Normal set without retardation, even when overdosed. Improved density and surface finish.
2. High water reducing rate. 40% increase in 28 day strengths. High strengths after 8 hours.
Compatible with Portland cement, Normal Portland cement, Portland Slag Cement, Flyash Cement, Portland Pozzolanic Cement, etc.
3. Improve workability (slump) of concrete when added into mixing truck


1. Disperse dyes, reactive dyes, vat dyes dispersant, leveling agent.
Pesticide Dispersing agent, fillers, leather tanning agents,
3. Concrete water reducer, oil well cement water reducing agent.

4. Used for water-based paints, pigment pastes efficient dispersant.
5. Paste used as a dispersing agent in acrylic series, Series C. aldehyde, chlorine partial series of latex paint.

6. In the paper industry as slime control, reduce sides, improve filler or fines retention, improved sizing
7. lower paint viscosity.
8. Sodium naphthalene sulfonate can also be used as adhesives, powder filling and sealing layer polymers to improve water resistance.
