concrete water reducing admixtures SNF naphthalene superplasticizer
Sodium Naphthalene Sulphonate Formaldehyde Condensate is Sodium
salt of naphthalene sulfonate polymerized with formaldehyde, also
called sodium naphthalene formaldehyde(SNF), poly naphthalene
sulfonate formaldehyde(PNS), Naphthalene Sulphonate
formaldehyde(NSF),naphthalene based high range water reducer,
Sodium naphthalene formaldehyde is a chemical synthesis of
non-air-entertainment superplasticizer, which has a strong
dispersibility on cement particles, thus produces concrete with
high early and ultimate strength.As a high range water reducing
admixture,sodium naphthalene formaldehyde has been widely used in
prestress, precast, bridge, deck or any other concrete where it is
desired to keep the water/cement ratio to a minimum but still
achieve the degree of workability necessary to provide easy
placement and consolidation.Sodium Naphthalene sulphonate
formaldehdye can be added directly or after dissolved. It can be
added during mixing or added directly to the freshly mixed
concrete. The recommand dosage is 0.75-1.5% by weight of cement.

1. Widely used in precast & ready-mixed concrete, armored
concrete and pre-stressed reinforced concrete in key construction
projects such as dam and port construction, road building &
town planning projects and dwelling erections etc.
2. Suitable for preparation of early-strength, high-strength,
high-anti-filtration and self sealing&pumpable concrete.
3. Used for and widely for self-cured, vapor-cured concrete and its
formulations. At the early stage of application, extremely
prominent effects are shown. As the result, the modulus and site
utilization can be drastically, the procedure of vapor cure is
omitted in peak heat summer days. Statistically 40-60 metric tons
of coal will be preserved when a metric ton of the material is
4. Compatible with Portland cement, normal Portland cement,
Portland slag cement, flyash cement and Portland pozzolanic cement
Because of the high dispersion force and low foaming
characteristics, SNF has also been widely used in other industries
as Anionic Dispersing Agent.
Dispersing agent for disperse, vat, reactive and acid dyes, textile
dying, wettable pesticide,paper,electroplating, rubber,
water-soluble paint, pigments,oil drilling, water treatment,carbon
