For professionals navigating the complexities of chemical procurement and application across various industries, a thorough understanding of key chemical auxiliaries is vital. Dispersant NNO, known chemically as Sodium Salt of Naphthalene Sulfonate Formaldehyde Condensate (CAS 36290-04-7), is one such indispensable compound. As a dedicated manufacturer and supplier, we aim to provide comprehensive insights into its properties and applications, empowering you to make informed purchasing decisions.

Dispersant NNO is an anionic surfactant characterized by its beige-brown powder appearance and excellent solubility in water of any hardness. Its molecular formula, C21H14Na2O6S2, signifies a complex structure that endows it with unique functionalities. Crucially, it possesses strong dispersing and protective colloid properties. Unlike some surfactants, it lacks surface activity such as permeability or foaming, making it ideal for applications where these are undesirable. Its affinity for protein and polyamide fibers, contrasted with its lack of affinity for cotton and hemp, also defines its specific uses.

The primary industrial application of Dispersant NNO lies in its role as a dispersant for a variety of dyes, including disperse dyes, vat dyes, reactive dyes, and acid dyes. In textile dyeing and printing, it ensures that dyes remain finely divided, promoting even color penetration and preventing aggregation, which is critical for achieving uniform shades and high color fastness. Professionals seeking to buy Dispersant NNO for these applications benefit from its efficiency in grinding, solubilization, and overall dispersion.

Beyond textiles, Dispersant NNO is a valuable auxiliary in other sectors. In the leather industry, it acts as an auxiliary tanning agent, improving the dispersion of tanning agents and dyes for a more uniform and aesthetically pleasing leather finish. For paper manufacturers, it serves as a dispersant in wood pulp, preventing issues arising from asphaltum and resin condensation, and also functions as a precipitant for animal size. Furthermore, its utility extends to electroplating additives, where it contributes to bath stability and uniform coating deposition.
