Naphthalene Superplasticizer (SNF Water Reducer)
CAS Number: 36290-04-7
Sulfonated naphthalene formaldehyde (SNF) condensate superplasticizer is a classic second-generation water-reducing admixture delivering water reduction rates of 15–25%. It provides strong initial fluidity and early strength gain, making it well-suited for precast concrete and normal-strength ready-mix applications. The product is cost-effective and compatible with most Portland cement types.
