Kingsun - Sulphonated Naphthalene Formaldehyde (SNF)
Sulphonated naphthalene formaldehyde，also called sodium naphthalene sulfonate (SNF/PNS/FND/NSF) is a high-range water reducing admixture. Naphthalene-based superplasticizer has the advantages of high water reduction rate, neither retardation nor air entrainment, and strong adaptability. It can greatly improve the workability of concrete and reduce the water consumption for mixing, and can significantly increase the strength of concrete.

As the main masterbatch of various composite concrete admixtures, through compounding with other kinds of admixtures, naphthalene sulphonate can also produce concrete admixture series products for various engineering requirements. This product helps to improve the quality of construction projects, improve construction efficiency, reduce construction costs, and speed up project progress.
Sulphonated naphthalene formaldehyde is the most widely used concrete additive at home and abroad due to its simple operation, low price and relatively good performance. The SNF based admixture has superior performance and is widely used in important projects such as industry, civil construction, roads and bridges, ports, oil fields, water conservancy facilities, etc., and is widely praised by customers and society.
