Description

1-Naphthalenesulfonic Acid, Ammonium Salt, Polymer With Formaldehyde is a synthetic, water-soluble polymeric compound derived from naphthalene. This material is valued for its excellent dispersing and complexing properties in aqueous systems. It serves as a critical functional additive in industries such as construction, textiles, and agrochemicals, where it enhances product performance and process efficiency.

Application

• Concrete Plasticizer & Dispersant: Acts as a highly effective water-reducing agent and superplasticizer in cement and concrete formulations to improve workability and strength.
• Textile & Leather Auxiliary: Used as a dispersing and leveling agent in dyeing processes and as a tanning auxiliary to ensure uniform color and material quality.
• Agrochemical Formulations: Functions as a dispersant and stabilizer in the production of wettable powders, suspension concentrates (SC), and other pesticide formulations.
• Pigment & Dye Dispersant: Enhances the dispersion and stability of pigments and dyes in paints, inks, and coatings, preventing agglomeration.
• Industrial Cleaning & Scale Inhibition: Serves as a key component in detergent builders and industrial water treatment chemicals for scale and corrosion control.
• Ceramic & Clay Processing: Improves the rheology and plasticity of ceramic slips and clay bodies, aiding in shaping and molding processes.

Quality Control

Our production of 1-Naphthalenesulfonic Acid, Ammonium Salt, Polymer With Formaldehyde adheres to stringent quality management protocols. Each batch undergoes rigorous testing for key parameters including sulfonation degree, molecular weight distribution, and dispersing performance. Certificates of Analysis (COA) documenting purity, pH, solid content, and other critical specifications are available upon request to ensure compliance with your application requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C/59-77°F). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which may affect product performance.
