Description

Benzenesulfonic Acid, Hydroxy-, Polymer With Formaldehyde, Phenol And Urea, Ammonium Salt is a synthetic, water-soluble polymer designed for high-performance applications. This specialized ammonium salt of a phenolic resin sulfonate offers excellent dispersing and complexing properties, making it a critical additive in demanding industrial processes. It is primarily utilized by manufacturers in the water treatment, construction, textile, and pigment dispersion industries seeking to enhance product stability and process efficiency.

Application

• Water Treatment: Acts as a highly effective scale and corrosion inhibitor in cooling water, boiler water, and reverse osmosis systems.
• Construction Chemicals: Used as a superplasticizer and dispersing agent in concrete admixtures to improve workability and reduce water content.
• Pigment & Dye Dispersions: Provides superior stabilization and prevents agglomeration in the production of paints, inks, and textile dyes.
• Oilfield Chemicals: Serves as a clay stabilizer and dispersant in drilling muds and completion fluids.
• Industrial Cleaning: Functions as a detergent builder and dispersing agent in heavy-duty alkaline and acid cleaners.
• Paper & Pulp Industry: Utilized as a dispersant for kaolin and calcium carbonate in paper coating formulations.
• Textile Processing: Aids in dye leveling and acts as an anti-precipitant in various dyeing and printing processes.
