Disodium Naphthalene Sulfonate Formaldehyde Condensate
Disodium Naphthalene Sulfonate Formaldehyde Condensate (CAS: 9084-06-4) is a polymeric anionic dispersant produced by condensing naphthalene sulfonate with formaldehyde, creating a molecular scaffold with multiple sulfonate groups along a hydrophobic backbone. This tan to brown powder is one of the most effective dispersants for cement, pigments, and minerals in aqueous systems. In concrete technology, it serves as a high-range water reducer (superplasticizer) dramatically improving flow and enabling high-strength, low-water formulations. The dye industry employs it to disperse vat and disperse dyes uniformly, while pigment manufacturers use it to stabilize colorant slurries. Additional applications include coal water slurry stabilization, pesticide wettable powders, and leather tanning auxiliaries. Its thermal stability, electrolyte tolerance, and strong adsorption on particle surfaces make this condensate indispensable for high-performance dispersion in demanding industrial processes.
– Superplasticizer Applications: Used as a high-range water reducer in concrete enabling self-compacting flows and high-strength cement formulations.
– Dye Dispersion: Serves as a dispersing agent for vat, disperse, and reactive dyes ensuring uniform shade and preventing aggregation.
– Pigment Slurries: Applied in stabilizing aqueous pigment dispersions for coatings, inks, and colorant manufacturing.
– Agricultural Formulations: Employed as a dispersant in wettable powder and water-dispersible granule pesticide formulations.
