Description

1,3-Benzenedicarboxylic acid, 5-sulfo-, monosodium salt, polymer with 1,2-ethanediol, 2-ethyl-2-(hydroxymethyl)-1,3-propanediol, hexanedioic acid, 2-hydroxyethyl 2-propenoate, 5-isocyanato-1-(isocyanatomethyl)-1,3,3-trimethylcyclohexane and 2,2-oxybisetha is a specialized, high-performance water-soluble sulfonated polyester polyol designed for demanding industrial applications. This advanced polymer combines the structural integrity of aromatic components with the hydrophilic and reactive functionality of sulfonate and hydroxyl groups. It is engineered for formulators seeking to enhance the durability, adhesion, and dispersion properties of coatings, adhesives, and composite materials. Key industries utilizing this polymer include advanced coatings, textile finishing, and specialty polymer synthesis.

Application

• Waterborne Polyurethane Dispersions (PUDs): Acts as a key hydrophilic component and internal emulsifier to create stable, high-performance aqueous PU coatings for textiles, leather, and plastics.
• High-Performance Coatings: Imparts excellent adhesion, chemical resistance, and flexibility in industrial, automotive, and protective coatings.
• Textile Finishing Agents: Used to create durable, breathable, and water-resistant finishes on fabrics.
• Adhesives and Sealants: Enhances bonding strength, moisture resistance, and flexibility in structural and pressure-sensitive adhesive formulations.
• Composite Materials: Serves as a compatibilizer and toughening agent in fiber-reinforced polymer composites.
• Ink Receptive Layers: Used in the formulation of coatings for specialty papers and films to improve print quality and adhesion.
• Crosslinking Agent for Polymers: Provides reactive sites for further chemical modification, enhancing network density and performance.

Quality Control

Our production of this sulfonated polyester polyol adheres to stringent ISO 9001 quality management standards. Every batch undergoes comprehensive analysis to ensure consistent performance, including tests for acid value, hydroxyl value, sulfonate content, viscosity, solids content, and color. Certificates of Analysis (COA) detailing all specifications are provided with each shipment. We support compliance with REACH and other global regulatory frameworks.

Storage

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