Product Description SODIUM NAPHTHALENE FORMALDEHYDE General Description: SNF's full name is Sodium Naphthalene Sulfonate Formaldehyde Condensate. Its high purity makes cement particles with high dispersancy, low foaming, high range water reducing and obvious strengthening so that we can accelerate project mould turnover and construction speed, and save cement, and also improve cement mobility and workability. SNF is a high range concrete admixture of concrete cast-in-place, prefabricating, pump and curing.
