Sodium Naphthalene Sulfonate Formaldehyde Best price

Sodium Naphthalene Sulfonate Formaldehyde has the advantage of high water reducing ratio, non-delayed coagulation, non-air entraining and strong adaptability. It can improve the workability of concrete to a large extent so as to reduce the water consumption for blending. Meanwhile, it can improve the strength of concrete. As the main master batch of various kinds of compound concrete admixture, it could also produce series products of concrete admixture which can be suitable for all kinds of project requirement through compounding with other kinds of admixture. This product can contribute to the improvement of project quality and construction efficiency and the reduction of construction cost. It can also improve the process of works.

Sodium Naphthalene Sulfonate Formaldehyde usage
1. As the requirement of engineer,the dosage can be adjusted after testing.
2. It can be put into blender with minxing water, If it is added later or added before concrete pouring and is mixed for a moment,the plasticizing effect could be better.
