Product Description High Range Water-Reducing Admixture Sodium Naphthalene Sulphonate Formaldehyde, Poly Naphthalene Sulfonate Formaldehyde Condensate,Concrete Admixture Uses Sodium Naphthalene Sulphonate Formaldehyde produces concrete with extremely workable characteristics referred to as high slump. PNS also allows concrete to be produced with very low water/cement ratios at low or normal slumps. Sodium Naphthalene Sulphonate Formaldehyde is ideal for use in prestress, 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 Sodium Naphthalene Sulphonate Formaldehyde Specification: Solid Content :93% PH value :8.42 Chlorides Content :0. 39% Sodium Sulfate Content :16% Addition Rates Sodium Naphthalene Sulphonate Formaldehyde can be added directly or added in after melt. It can be added during mixing and after-mixing. The afterward approach can achieve better result. The suggested addition rate is 0.75%. Sodium Naphthalene Sulphonate Formaldehyde Direction Prepare solutions as required. Direct use of powdery agent is allowed. Alternatively the addition of the agent is followed by water moisturization (water-cement ratio: 60%). The agent can be combined with other externally applied agents if pilot development or laboratory experiment succeeds.

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.
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.
