Naphthalene Sulfonate Formaldehyde Condensate (NSF)

Keywords: Superplasticizers,Naphthalene, Sulfonate, formaldehyde, condensate, PNS, FDN

 

NSF full name is Naphthalene Sulfonate formaldehyde condensate. Its high purity makes cement paticles with high dispersancy, low foaming, high range water reducing and obvious strengthening so that we can get advantages of accelerating project mould turnover and construction speed, and also saving cement, improving cement mobility and workability.
