Description

Hexanedioic Acid, Polymer With 1,4-Butanediol, 1,6-Diisocyanatohexane And 1,6-Hexanediol, 2-[(2-Aminoethyl)Amino] Ethanesulfonic Acid-Modified, Sodium Salt is a specialized, sulfonated polyurethane polymer designed to impart unique ionic and hydrophilic characteristics to materials. This product matters for formulators seeking to enhance the water compatibility, antistatic properties, or dyeability of polymer systems without sacrificing structural integrity. Industries such as textile coatings, specialty adhesives, and biomedical materials utilize this modified polymer to achieve specific performance targets in advanced applications.

Application

• Textile Finishing Agent: Used as a hydrophilic modifier and antistatic agent in synthetic fiber coatings and finishes.
• Specialty Polyurethane Dispersions (PUDs): Serves as an ionic monomer or chain extender to create self-emulsifying, water-based PU dispersions for eco-friendly coatings.
• Biomedical Material Modifier: Imparts enhanced biocompatibility and moisture management properties to polyurethane-based wound dressings or tissue engineering scaffolds.
• Adhesive & Sealant Formulation: Incorporated to improve adhesion to polar substrates and adjust the moisture-curing profile of polyurethane adhesives.
• Dye-Receptive Polymer Additive: Enhances the dye uptake and color fastness of polyurethane fibers and films.
• Antifogging Coatings: A key component in formulations for transparent films and lenses where moisture absorption prevents fogging.

Quality Control

Our production of this specialty polymer adheres to strict batch-to-batch consistency protocols. Quality is verified through parameters including ionic content, solution viscosity, pH, and residual monomer levels. A comprehensive Certificate of Analysis (COA) detailing lot-specific results is provided with every shipment to ensure it meets your formulation requirements.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive). Store in a cool, dry place at room temperature (15-25°C/59-77°F) with low humidity. Ensure the container is kept sealed when not in use to prevent moisture absorption, which can affect product performance.
