Sodium Naphthalene Sulfonate Formaldehyde (FDN)

A kind of yellow powder naphthalene-based superplasticizer

Sodium Naphthalene Sulfonate Formaldehyde

Commodity Name:

Naphthalene Sulfonate Formaldehyde/Poly Naphthalene Sulfonate (SNF/NSF/PNS)

Product Introduction:

FDN superplasticizer can be applied to make flowable, strong or steam-curing concrete. It is particularly used as the base material for compound admixtures. FDN possesses the features of no retarding, no air-introducing, superplastic high water-reducing, and strength enhancing. It has low alkali content, low sulfonate, and high purity. It can be widely used in different concretes with less dosage and easy to use.

Product Features:

  • Powerful plasticizing action with improved initial workability.
  • Reduces water-cement ratio to the maximum which allows the production of high strength concrete while saving cement use.
  • Improved cohesion and particle dispersion minimizes segregation and bleeding and improves pumpability.
  • Long haul and hot weather concreting.
  • Gains early strength with very high slump retention.

Product Type:

Brown powder

Packaging & Storage:

25 kg of plastic bags with PE liners, 25kg PP woven bags, or packed according to customer requirements.
