Product Description:

Sodium Naphthalene Formaldehyde

Naphthalene Sulfonate Formaldehyde Condensate Chemical Additives

 (NZY-FN1/FN2/FN3 Na2SO4 ≤5%/10%/18%)

Description

Sodium Naphthalene Sulfonate Formaldehyde water reducing admixtue,chemical name β-naphthalene sulfonate 

formaldehyde condensate ,will result in better dispersion of cement agglomerates.  The series products of naphthalene

superplasticizer have been widely used in: roads, bridges, ports, docks, water  and electricity facilities, industrial and  

civil construction, prefabricated concrete and other concrete engineering


Naphthalene Sulfonate Formaldehyde Condensate Chemical Additives

Applications

1.         NSF is suitable to make high flowing concrete, commercial concrete, pumping concrete, precast and reinforced 

concrete.

2.         NSF can be used to make C10-C60 concrete with slump loss between 50mm and 70mm, or C60 concrete with 

slump between 180mm and 220mm

3.         NSF can be used as raw material to compound accelerator, retarder, anti-freezing agent and pumping aid to satisfy

 requirements from different construction projects, techniques, materials and environmental temperatures.

4.         NSF is compatible with Portland Cement, Portland Slag cement, Fly-ash Cement, Portland Pozzolanic Cement etc

Features and Benefits

Non-toxic, non-irritating and no corrosion to steel bars

High water reducing rate: up to 25%

Strengthening ability

Improving concrete durability and impermeability

Appropriate setting time

Good compatibility with various types of cement

Dosage and Usage

1. The dosage is about 0.5 ~ 1.5% of cementitious materials, actual usage needs to be confirmed by the test

2. Due to the adaptive differences between different types of the cement and admixtures. The adaptive test of cement and admixture should be done before using or changing the cement type.

Packaging, transport and storage

1. The powder product is packed with 25 ± 0.25kg laminating woven bag. Packaging specifications should meet the user 

requirements.

2. Powder product is easy to soluble in water, liquid dilution will affect the effective concentration of the product, transport and

 storage should be noted that the anti-leaching, avoid moisture, direct sunlight, kept under seal and away from open flame at 

the room temperature or during the transport.

3. In the case of good storage conditions, valid period is three years. If it is more than 3 years, rechecking is needed for using

 continually.
