Naphthalene Based Superplasticizer

SNF superplasticizer is an anion surface active agent based on polyalkyaryl sulfonate. Having a strong dispersion effect on cement, it is a kind of highly effective, low air-entrained water-reducing agent with effective water reduction and low air-entrainment.

Product Details

Naphthalene formaldehyde sulphonate water reducing agent is a synthetic powder based on beta-sulphonate formaldehyde condensate and reactive polymer. Sodium naphthalene sulfonate cement particles have a very strong dispersion. Preparation of large fluidized

concrete, pouring concrete with high early strength, high strength requirements and system components, have a very good effect, to fully enhance and improve various properties of concrete.
