Описание

Sodium salt of polynaphthalene sulphonic acid or sodium naphthalene sulphonate formaldehyde (SNF/PNS/FND/NSF), also known as sodium polynaphthalene sulphonate or sulphonated naphthalene formaldehyde, is commonly known as high efficient water reducing agent for concrete. SNF has strong dispersing effect on cement particles, and the water reduction rate can reach 15-25%. It is especially suitable for the preparation of high-strength concrete, steam-cured concrete, fluid concrete, impermeable concrete, waterproof concrete, plasticised concrete, reinforced and prestressed concrete. concrete, reinforced and prestressed reinforced concrete.

Характеристики
