Description

2-Naphthalenesulfonic Acid, Sodium Salt, Polymer With Cyanoguanidine And Formaldehyde is a synthetic, water-soluble polycondensate polymer. This specialized chemical is engineered to function as a highly effective dispersant and complexing agent in demanding industrial processes. It is primarily required by manufacturers in the textile, construction, and water treatment industries for its ability to control scale, stabilize formulations, and improve process efficiency.

Application

• Textile Auxiliary: Acts as a powerful dispersing agent for dyes and pigments, ensuring uniform coloration and preventing agglomeration.
• Construction Chemical: Used as a superplasticizer and water-reducing agent in concrete admixtures to improve workability and strength.
• Scale Inhibitor: Effective in industrial water treatment systems for boiler and cooling water to prevent calcium carbonate and sulfate scale formation.
• Dispersant for Ceramics & Paints: Stabilizes particulate suspensions in ceramic slips, coatings, and pigment preparations.
• Tanning Agent: Employed in the leather industry as a syntan (synthetic tanning agent) to aid in the tanning process.
• Paper Manufacturing: Serves as a retention aid and dispersant in pulp processing.
