Uses
Concrete: SNF water reducing agent can improve the strength and durability of concrete by increasing its fluidity and reducing its viscosity, reducing the amount of cement used. In addition, SNF water reducing agent can also reduce concrete surface cracks and shrinkage.
Cement products: SNF water reducing agent can be used to manufacture cement mortar, blocks, pipes, floor tiles, and other cement products to improve their fluidity, reduce the amount of cement used, improve strength, and reduce shrinkage.
Mortar: SNF water reducing agent can be used to manufacture mortar to improve its fluidity, increase viscosity, increase setting time, and reduce shrinkage.
Other fields: SNF water reducer can also be used in the manufacturing of casting, pulp, asphalt, and other fields. In these fields, SNF water reducing agents can be used as adhesives, dispersants, and thickeners to improve the performance of materials and processing processes.

Cautions of sodium naphthalene sulfonate formaldehyde condensate
Prevented from being tom by sharp-ended objects while packages are being transferred or delivered. When being contaminated by high humidity or moisture in case of leakage, it can be prepared in prescribed ways for further use without surrendering any effect.
Storage of sodium naphthalene sulfonate formaldehyde condensate
SNF Superplasticizer should be stored in a dedicated warehouse that is well-ventilated and dry. If SNF Superplasticizer be affected with damp, just smash or melt it into a solution without any bad effection.
Wanshan Chemical Introduction
Shandong Wanshan Chemical Co., Ltd is a whole owned subsidiary of Shandong Wanshan Group Co., Ltd. As an ISO 9001:2008 certified firm, Shandong Wanshan Chemical Co., Ltd is the largest manufacturer of a kind of concrete admixture: SNF (Sodium naphthalene formaldehyde powder) in China.
Factory Show
Our factories have realized scale production, we produce the raw material of formaldehyde by ourselves, and we buy the raw material of industrial naphthalene from our neighbor factory which is 50 meters from us. The coal gas we used is produced by ourselves. All those reduce our production costs, so we can offer the best price.

Concrete Admixture Sodium Naphthalene Sulfonate Formaldehyde Condensate(SNF, FDN, SNF Powder)
Superplasticizer admixture for concrete is a synthetic powder based on beta-sulphonate formaldehyde condensate and reactive polymer.
CAS Number: 36290-04-7
HS Code (CN): 38244010
Sodium naphthalene formaldehyde sulphonate condensate is a high range water reducer, commonly referred to as a super plasticizer, also named Naphthalene Sulphonate Formaldehyde Condensate (short name: SNF, PNS, FDN, etc…)
Sodium naphthalene formaldehyde sulphonate condensate is made from naphthalene, sulfuric acid, formaldehyde and liquid alkali, through sulfonation, hydrolyzation, condensation and neutralization reaction and then drying to powder. SNF-A 5% contains very small chloride. Thus, it meets the requirements of chemical admixture specifications for concrete: GB 8076-2008.
Properties of Sodium Naphthalene Sulfonate Formaldehyde(CAS 36290-04-7)
1. Appearance: Light brown powder& dark brown liquid. Non-poisonous, odorless, non-flammable and non-corrosive to steel bars.
2. Remarkable Plasticity: As a condition of blending where the amount of cement and collapsibility are fixed aforehand, mixing water can be decreased by 18-28% when it is admixed with reinforced concrete at 0.5-1.0%. Statistically, compression strength on the 1st day, the 3 rd day and the 28th day after a single application is increased by 60-90% and 25-60% respectively when it is added at standard blend dosage. As the result, compression strength, tensile strength, buckling strength and modulus of elasticity will be improved to some extent
3. Improve miscibility of concrete amalgamator with water and collapsibility as well. As a condition of equivalent blending, collapsibility can be increased 5-8 times when it is added at 0.75% blend dosage.
4.15-20% of cement can be reserved when the agent is blended at 0.75% blend dosage, which is preconditioned by the same collapsibility and strength.
Applications of Sodium Naphthalene Sulfonate Formaldehyde(CAS 36290-04-7)
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 decks, 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.
Detailed Usages of Sodium Naphthalene Sulfonate Formaldehyde(CAS 36290-04-7)
1 .Blending dosage at 0.5%-1.0%, 0.75% mixing dosage advised.
2. Prepare solutions as required.
3. Direct use of powder agent is allowed. Alternatively, the addition of the agent is followed by water moisturization (water-cement ratio:60%).
4. The agent can be combined with other externally applied agents if pilot development or laboratory experiment succeeds.
Advantages of Sodium Naphthalene Sulfonate Formaldehyde(CAS 36290-04-7)
SNF produces high slump flowable concrete with no loss in strength. SNF produces low water/cement ratio concrete and therefore, high strengths. SNF in prestress/precast work can be used to substantially reduce or eliminate the high energy requirements of external heat for accelerated curing. SNF concrete, even at a high slump, exhibits no significant segregation in comparison to concrete without a super-plasticizer at the same slump. SNF aids in the rapid discharge of concrete from truck mixers thereby reducing on-the-job time and improving mixer utilization.
