Sodium Naphthalene Formaldehyde (SNF-Superplasticizer for Concrete)
CAS Code: 36290-04-7
SNF a high range water reducer, commonly referred to as a super plasticizer, also named Naphthalene Sulphonate Formaldehyde Condensate (short name: SNF, PNS, NSF, etcâ?¦)
SNF is made from naphthalene, sulfuric acid, formaldehyde and liquid alkali, through sulfonation, hydrolyzation, condensation and neutralization reaction and then drying to powder. SNF-A5% contains very small chloride. Thus, it meets the requirements of chemical admixture specifications for concrete: ASTM Designation C 494 as a Type F admixture, GB8076-2008 and GB50119-2003.
Usage
SNF produces concrete with extremely workable characteristics referred to as high slump.
SNF also allows concrete to be produced with very low water/cement ratios at low or normal slumps.
SNF is ideal for use in pre stress, precast, bridge deck or any concrete where it is desired to keep the water/cement ratio to a minimum and still achieve the degree of workability necessary to provide easy placement and consolidation.
SNF will also fluidize concrete, making it ideal for tremie concreting or other applications where high slumps are desired.
SNF is compatible with Portland Cement, Normal Portland cement, Portland Slag Cement, Fly-ash Cement, Portland Pozzolanic Cement, etc.
Description
YL-SNF-A is a high range water reducer, high concentration naphthalene-based superplasticizer, also named Naphthalene Sulfonate Formaldehyde Condensate (NSF), SNF, PNS and FDN etc.
YL-SNF-A (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, complying with ASTM C 494, Type F. ASTM C 1017, GB8076-2008 and GB50119-2003 etc.
Uses
1.YL-SNF-A possesses the features of no retarding, no air-introducing, superplastic high water-reducing and strength enhancing. It has no chloride, low alkali content, low sulphonate, and high purity. It can be widely used in different concretes with less dosage and easy to use.
2.YL-SNF-A can be applied to make flowing, strong or steam-curing concrete. The minimum working temperature can be as low as zero centigrade degree. In steam curing, concrete with superplasticizer has to be strong enough before heating. The steam curing specification has to be pre-tested. It is particularly used as base material for compound admixtures.
3.It can prevent from the alkali-aggregate reaction because of the biggish alkali reactivity of aggregate or the alkali-aggregate reaction in the moist environment.
Advantage
1.High water-reducing rate: YL-SNF-A can reduce water 20-30%. It has features of superplasticizer, effectively increases concrete fluidity and reduces water penetration and segregation and improves the encapsulation force of the concrete with reinforcing steel bar.
2.Strengthening: Given the same amount of cement and slump requirement, this product with the dosage 0.5-1.2% can increase the concrete early strength and reinforced effect by 50-100%, 40-70%, 25-60% and 20-60% on day 1, 3, 7, and 28 respectively.
3.High applicability: It can be used with different variety of cement. It is compatible with other admixtures.
4.Low sodium Sulfate content: The aqueous solution has no crystals in winter, which can avoid pipeline congestions when JK-01 NP applied. It is suitable for automatic working.
5.Effective durability: It can modify the structure of concrete and increase the property of anti-seepage, anti-freezing, and carbonization.
6.Easy to use: It can be added directly or used after dissolved in water. It can be used for different working condition and concrete mixer.

Sodium Naphthalene Sulphonate Formaldehyde is widely applicable for cements builing,especially for the following: fluid cement, plasticized cement, steamed cement, water-tight cement, water-proof cement, prefabricated cement, prestressed reinforced cement and high strength cement. But the adaptability to different kind of cement is different.
Sodium naphthalene sulphonate formaldehyde(snf): snf used as dispersing agent in dyestuff , super plasticizer, high range water reducing agent in construction field, concrete admixtures.
Sodium Naphthalene Sulfonate Formaldehyde
This product, named -naphthalene sulfonate formaldehyde condensate, is non-air entraining superplasticizer. It has good
dispersing performance to the cement particles. Compared with traditional plasticizer, it has higher water reducing rate, and good for preparing mass concrete, fresh concrete required for early strength and high strength, and precast concrete and parts. It also has good adaptability to commonly used cement, and widely used in roads, bridges, dams, power engineering, civil construction, steam and natural curing precast parts and other projects.
Advantage:
* Higher water reducing rate. By the recommended dosage, the water reducingrate can reach 15% -20%.
* Improve the workability of concrete, such as compression, long-term strength, flowability, etc., and enhance the reinforcement of steel and concrete.
* Reduce costs. In the case of maintaining the same workability and strength, cement amountcan be reduced.
* Wide adaptability, cost-effective. Good adaptability to all kinds of cement, such as Portland cement, slag cement, volcanic ash cement, etc.
* Be mother material to formulate other admixtures.(like early strength, set retarder, pumping agent, antifreezing agent).
