Description
JK-01NP Sodium Naphthalene Sulfonate Formaldehyde CAS 36290 04 7 is a kind of high efficiency water reducer for concrete and mortar. Other name: Poly Naphthalene Sulfonate Formaldehyde Condensate, Naphthalene Righ Range Water Reducer, Naphthalene Based Superplasticizer, Naphthalene Superplastizier, High Efficient Water Reducing Agent, High rage water reducing admixture, PNS, SNF, FDN.
Uses
JK-01NP Sodium Naphthalene Sulfonate Formaldehyde CAS 36290 04 7 In the construction market Sodium Naphthalene Sulfonate Formaldehyde plays a very important role as an admixture in concrete, cement, gypsum, and mortar mixes known as superplasticizer. Concrete superplasticizer can improve the rheology, mechanical, and flow properties of concrete while increasing concrete strength, promoting compaction, and providing optimium workability.
Technical Feature
- Sodium Naphthalene Sulfonate Formaldehyde can reduce the water consumption without affecting the normal construction of concrete, in the hardening process of concrete, there is less water to be lost, there are fewer internal air holes in the concrete, which increase the strength of the concrete.
- Sodium Naphthalene Sulfonate Formaldehyde can improve the workability of concrete and reduce the energy consumption of construction mixing.
- Sodium Naphthalene Sulfonate Formaldehyde can reduce the amount of cement and water without reducing the performance and mechanical index of cement concrete, thus reducing the construction cost.

Dosage
0.5 – 1.5% by weight of cement. Exact dosage rates are dependent on the type of effect sought, quality of cement and aggregates, water/
cement ratio and ambient temperature. Therefore, in many cases it is advisable to carry out trial mixes.
Sodium Naphthalene Sulfonate Formaldehyde can be added directly or added in after dissolved in water. It can be added during mixing
and after-mixing (better). The after-mixing approach can achieve better result.
Package, Storage & Shelf Life
For powder: Powder packed in 25kg bag/650kg/700kg jumbo bag.
It should be stored in a dedicated warehouse that is well-ventilated and dry and keep away from moisture.
Shelf Life: Minimum 24 months. After the expiration date, it can be used if testing results is qualified.
