Water reducer admixture is a stable dispersion of stearate
other water repellent compounds

Specifications

 1.Big Naphthalene Sulphonate agent factory
2.High-water reducing agent
3.Solid content:92% min
4.Low dosage

Product Description

FDN is made of naphthalene, sulfonic acid, formalin and alkali, through sulphuration, hydrolyzation, condensation and neutralization reaction.

FDN have many advantage of :no chloride,good dispersion, water reduction and early-strength effect,good dispersion, water reduction and early-strength effect,without air entraining , no corrosion on steel bars , good compatibility with portland cement .

Concept

Products meets the requirements of chemical admixture specifications for concrete:

ASTM Designation C 494 as a Type F admixture,GB8076-1997 and GB50119 2003.

We are the supplier of Chryso(South Afric and India market) and BASF(Saudi Arabia markat) based our high quality,good service and long L/C payment days.

Appearance: Powder, light brown hollow particle. Liquid, brown-yellow liquid.
