waterproof concrete additive

Product Name: Sodium Naphthalene Sulfonate Formaldehyde Condensate (SNSF) Other name: poly naphthalene sulfonate (PNS), sodium naphthalene sulphonate (SNS) Product Identification & Application: Its high purity makes cement particles with high disapersancy, 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. SNSF has a good adaptability to various cements and it is no erodent to reinforcing bar and nonpoisonous and pollution-free. SNF has been applied to the highway, bridge, tunnel, water conservancy hydroelectric project, port, quay, skyscraper, power engineering, industrial civil building, prestressing force component and high range concrete etc. Chemical Compositions: Packing: In 25kg PP bag or 650kg jumbo bag Storage and shelf life: 12 months under cool, dry condition in original packing away from heat sources.
