Product Description:

Naphthalene Sulfonate Formaldehyde (PNS)
(Na2SO4 ≤18%)


Description
PNS, a high range water reducer with no air entraining component, is also named as Naphthalene Sulfonate Formaldehyde Condensate (NSF), SNF, PNS, etc.. It complies with chemical admixture specifications for concrete: ASTM C 494, Type F; ASTM C 1017.

Application
1. PNS is suitable to make autotrophic concrete, steam curing concrete, steel concrete and prestress concrete, all of which are made mainly of portland cement.
2. PNS is applicable in areas with the daily lowest temperature of 0
and for making concrete which requires high fluidity, high strength or steam curing.
3. PNS can be used to make C80 concrete with slump loss between 50mm and 70mm, or C60 concrete with that between 180mm and 220mm.
4. PNS can be used as a raw material to compound accelerator, retarder, anti-freezing agent and pumping aid to satisfy requirements from different construction projects, techniques, materials and environmental temperatures.
5. PNS is compatible with Portland Cement, Portland Slag Cement, Fly-ash Cement, Portland Pozzolanic Cement, etc.
