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 :96.42% PH value :8.3 Chlorides Content :0.25% Sodium Sulfate Content :4.4% If you are interested in our products, please do not hesitate to contact us!
