Product Description
Poly Naphthalene Sulfonate Formaldehyde PNS is a kind of naphthalene superplasticizer (SNF/FDN/PNS) is non-corrosive, non-chlorine compound antifreeze concrete admixture which has antifreezing, water-reducing, early-strength, air entraining, etc... performance,
it helps to lower the freezing point, prevent concrete from freezing damage etc.
It is ideal for construction in winter season.

Uses of Poly Naphthalene Sulfonate Formaldehyde PNS
To provide initial workability especially with low water cement ratio.
To significantly improve the initial workability of site mixed concrete without increasing water demand.
To provide improved durability by increasing ultimate strengths and reducing concrete permeability.
To have high slump retention with early setting time.
Typical Applications & Advantages of Poly Naphthalene Sulfonate Formaldehyde PNS
1. Powerful plasticizing action with improved initial workability.
2. Reduces water cement ratio to the maximum which allows production of high strength concrete while saving cement use.
3. Improved cohesion and particle dispersion minimizes segregation and bleeding and improves pumpability.
4. Long haul and hot weather concreting.
5. Gains early strength with very high slump retention

Dosage of Poly Naphthalene Sulfonate Formaldehyde PNS
The optimum dosage of Naphthalene Sulfonate Formaldehyde (SNF/ NSF /PNS) to meet specific requirements should always be determined by trials using the materials and conditions that will be experienced in use.
Our suggestions as below:
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%).
