Description

Sodium 3-Sulphonatopropyl Acrylate is a high-purity, water-soluble anionic monomer featuring both a polymerizable acrylate group and a sulfonate functionality. This unique structure is critical for imparting permanent negative charge, hydrophilicity, and excellent electrolyte compatibility to polymeric materials. It is an essential raw material for manufacturers in the water treatment, personal care, and advanced materials sectors seeking to enhance product performance through ionic modification.

Application

• Superabsorbent Polymers (SAPs): Key monomer for producing high-performance, salt-tolerant superabsorbents used in hygiene products (diapers, adult incontinence pads) and agricultural hydrogels.
• Water Treatment Chemicals: Serves as a functional co-monomer in scale inhibition and dispersant polymers for industrial cooling water, boiler water, and reverse osmosis systems.
• Personal Care & Cosmetics: Used in the synthesis of rheology modifiers, film-formers, and stabilizers for shampoos, creams, and lotions, providing enhanced sensory properties and stability.
• Dispersants & Grinding Aids: Effective in the production of pigment dispersants for inks, coatings, and ceramic processing, improving color strength and particle suspension.
• Enhanced Oil Recovery (EOR): Incorporated into polyacrylamide-based polymers to improve viscosity and salinity tolerance in chemical flooding applications.
• Concrete Admixtures: Acts as a co-monomer in polycarboxylate ether (PCE) superplasticizers to control slump retention and water reduction in high-performance concrete.
• Textile & Leather Auxiliaries: Used in binders, finishing agents, and dyeing assistants to improve fabric handle, color fastness, and processing efficiency.
• Adhesives & Sealants: Imparts water solubility, adhesion, and crosslinking capabilities in specialty adhesive formulations.

Quality Control

Our Sodium 3-Sulphonatopropyl Acrylate is manufactured under a stringent quality management system. Each batch undergoes comprehensive analytical testing, including assay, impurity profiling, and physical characterization, to ensure consistency and compliance with customer specifications. Certificates of Analysis (COA) documenting purity, residual monomers, and other critical parameters are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect product quality and handling properties.
