Sodium naphthalene sulfonate formaldehyde, also known as SNF/PNS/FND/NSF, can be used as a high-efficiency concrete water reducing agent. In fact, SNF water reducing agent is widely used in cement and construction industries. For example, it has strong dispersion to cement particles and high water reduction rate to concrete. When added to concrete, it can not only save cement and improve the compatibility of concrete, but also speed up the construction progress. This product has good effect on formulating many kinds of concrete such as high flow concrete. Besides, it can also improve the performance of concrete.

Sodium naphthalene formaldehyde is high range water-reducing and an anion surface active agent based on polyalkyaryl- sulphonate. Technical spefication: Solid content 92% min Moisture 8.0 % max Fineness 5.0% max Ph value 7 - 9 Chlorides content 2.0% max Surface tension 68-72 mn/m Cement flowing rate 230mm min Concrete reducing water rate 18% min Sodium sulfate content 18% max (5%max is also available) Sodium naphthalene formaldehyde produces concrete with extremely workable characteristics referred to as high slump. Pns also allows concrete to be produced with very low water/cement ratios at low or normal slumps.Sodium naphthalene formaldehyde is ideal for use in prestress, precast, bridge deck or any concrete where it is desired to keep the water/cement ratio to a minimum and still achieve the degree of workability necessary to provide easy placement and consolidation. Addition ratessodium naphthalene formaldehyde can be added directly or added in after melt. It can be added during mixing and after-mixing. The afterward approach can achieve better result. The suggested addition rate is 0.75%.Sodium naphthalene formaldehyde directionprepare solutions as required.Direct use of powdery agent is allowed. Alternatively the addition of the agent is followed by water moisturization (water-cement ratio: 60%).The agent can be combined with other externally applied agents if pilot development or laboratory experiment succeeds. Packed in plastic film bag wrapped with plastic woven sack with a net weight of 25kg each.
