SODIUM NAPHTHALENE FORMALDEHYDE

General Description:
SNF 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 get advantages of accelerating project mould turnover and construction speed, and also saving cement, improving cement mobility and workability. SNF is a high range concrete admixture of concrete cast-in-place, prefabricating, pump and curing.
