Naphthalene Sulfonate Formaldehyde (NSF) is a
naphthalene-based superplasticizer, also named
Naphthalene Sulfonate Formaldehyde Condensate and
Poly Naphthalene Sulfonate (PNS) etc. It is a
high range water reducer, commonly referred to as
superplasticizer. It is a chloride free product
thats supplied as a brown powder to be instantly
dissolved in water. Its used to effect
substantial water reduction to concrete without
influencing normal setting time.

  • Uses
  • To provide initial workability especially with
    low water cement ratio.
  • To significantly improve the initial workability
    of site mixed concrete without increasing water
    demand.
  • To provide improved durability by increasing
    ultimate strengths and reducing concrete
    permeability.
  • To have high slump retention with early setting
    time.

  • Typical Applications Advantages
  • Powerful plasticizing action with improved
    initial workability.
  • Reduces water cement ratio to the maximum which
    allows
  • production of high strength concrete while
    saving cement use.
  • Improved cohesion and particle dispersion
    minimizes segregation
  • and bleeding and improves pumpability.
  • Long haul and hot weather concreting.
  • Gains early strength with very high slump
    retention.

Dosage
The optimum dosage of Naphthalene Sulfonate
Formaldehyde (SNF/ NSF /PNS) to meet specific
requirements should always be determined by
trials using the materials and conditions that
will be experienced in use.
Setting Naphthalene Sulfonate Formaldehyde (SNF/
NSF /PNS) affords excellent control over initial
and final setting times. Setting times of
concrete mixes are related to cement type, mix
design and ambient temperature.

Packaging Storage
Its packed in woven fabric bag with plastic
liner. Net weight 25kg. Naphthalene Sulfonate
Formaldehyde (SNF/ NSF /PNS) has a minimum shelf
life of 12 months provided it is stored under
cover, out of direct sunlight.
8
Health Safety Precautions
Naphthalene Sulfonate Formaldehyde (SNF/ NSF
/PNS) does not fall into the hazard
classifications of current regulations. However,
it should not be swallowed or allowed to come
into contact with skin and eyes. Suitable
protective gloves and goggles should be worn.
Splashes on the skin should be removed with
water. In case of contact with eyes rinse
immediately with plenty of water and seek medical
advice. If swallowed seek medical attention
immediately and not induce vomiting.For further
information, refer the Material Safety Data Sheet
available for this product.
