SNF/FDN/PNS Naphthalene Superplasticizer Ready Mix Concrete Admixture
CAS No.: 36290-04-7 | HS Code: 38244010
SNF is a high range water reducer, high concentrate naphthalene-based superplasticizer, also named Naphthalene Sulfonate Formaldehyde Condensate (NSF), FDN, PNS, etc. It is made from naphthalene, sulfuric acid, formaldehyde and liquid alkali, through sulfonation, hydrolyzation, condensation and neutralization reaction and then drying to powder.
SNF possesses the features of no retarding, no air-introducing, superplastic high water-reducing and strength enhancing. It has low alkali content, low sulfonate, and high purity. It can be widely used in different concretes with less dosage and easy to use.
