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.

We are strong at researching and production of Lignin items, Polycarboxylate Superplasticizer, SNF, Sodium Gluconate ,Our Annual output is over 150,000 Mts. Description: Sodium lignosulfonate is first generation concrete admixture.It is made of wood pulp, a anionic surfactant. Has retarding effect and water reducing effect. Sodium lingosulfonate is yellow brown powder, can be combined into early strength agent, retarder, antifreeze, pumping agent, combined with naphthalene superplasticizer to liquid admixtures has no precipitate formed. Sodium lignosulfonate can be used as an admixture for polymers and concrete. It has the advantages of low cost and environmental friendliness.
Polycarboxylate superplasticizer 50% (High water reducing type) Polycarboxylate superplasticizer is a new generation of high performance polycarboxylic acid superplasticizer was prepared from methyl allyl alcohol polyoxyethylene ether macromonomer by free radical polymerization, it is containing 50% solid content. It has a higher water reduction rate and a certain slump protection function, to ensure the excellent working performance of concrete, higher strength and excellent durability, mainly used for export, transport distance is relatively long mother customers. Product Feature: 1.The higher water reduction rate can reach more than 40%. 2.Low viscosity and low thixotropy, It is more suitable for concrete with low water cement ratio
Calcium propionate(CAS No.4075-81-4) is a new type of food additive . It is a safe and reliable antifungal agent for food and feed approved by the World Health Organization ( WHO ) and the United Nations Foodand Agriculture Organization ( FAO ) . Calcium propionate has a wide range of antibacterialeffects on molds , yeasts and bacteria . It is harmful , harmless to humans and animals , and has notoxic side effects. Calcium propionate is easy to be mixed with flourevenly. As a preservative, it can provide necessary calcium for human body andstrengthen food.Calcium propionate is a new food preservative developed in in recent years.Compared with sodium benzoate, it has strongeranti-corrosion ability and is safer.Its preservative and preservation effectmakes it widely used as preservative and preservation of breads, pastries,cakes, fruits and pastries
