Sodium Naphthalene Sulphonate Formaldehyde Used For Concrete Cas No: 36290-04-7

Naphthalene series superplasticizer, nicknamed naphthalene sulfonate formaldehyde condensate, is a non-air-entraining superplasticizer synthesized by chemical industry. It has a strong dispersing effect on cement particles, has a good application effect on the preparation of large flow concrete, and has obvious effect on cast-in-situ concrete and prefabricated components with requirements of early strength and high strength. It can be improved and improved in an all-round way. The various properties of good concrete are widely used in highways, bridges, dams, ports, wharfs, tunnels, electric power, water conservancy and civil engineering, steam curing and natural curing prefabricated components, etc.
SNF have advantage of :good dispersion, water reduction and early-strength effect ,non-air entraining , no corrosion on steel bars , good compatibility with portland cement.
