Description

1,3-Benzenedicarboxylic acid, 5-sulfo-, monosodium salt, polymer with 1,3-diisocyanatomethylbenzene, 2-ethyl-2-(hydroxymethyl)-1,3-propanediol, hexanedioic acid, .alpha.-hydro-.omega.-hydroxypoly(oxy-1,2-ethanediyl) and 2,2-oxybisethanol, 2-oxepanone homo is a specialized, high-performance water-dispersible polyurethane polymer. This advanced material is engineered to provide exceptional film-forming properties, adhesion, and flexibility in demanding aqueous systems. It is a critical component for formulators seeking to enhance performance while meeting stringent environmental and regulatory standards for low-VOC and solvent-free products. Key industries that utilize this polymer include coatings, adhesives, textiles, and specialty chemical manufacturing.

Application

• Aqueous Industrial Coatings: As a primary film-forming agent in metal, wood, and plastic coatings, providing durability, chemical resistance, and excellent adhesion.
• Textile Finishing and Coatings: For producing soft, flexible, and waterproof finishes on fabrics, leather, and non-wovens.
• Adhesives and Sealants: Serving as a key binder in water-based adhesive formulations for packaging, laminates, and construction applications.
• Inkjet Receptive Layers: As a component in coatings for specialty papers and films to enhance ink adhesion, color vibrancy, and dry time.
• Fiber Sizing and Composite Binders: Improving the handling and interfacial properties of glass, carbon, and other reinforcing fibers.
• Personal Care & Cosmetic Films: Used in hair fixatives, sunscreens, and nail polish to form flexible, water-resistant films.

Quality Control

Our production of this specialty polyurethane dispersion adheres to a strict quality management system. Every batch undergoes rigorous in-process and final testing to ensure consistent performance parameters such as solids content, viscosity, pH, particle size, and mechanical film properties. Certificates of Analysis (COA) documenting these specifications are provided with each shipment. We support compliance with global regulatory frameworks, including REACH.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 15°C and 25°C (59°F - 77°F). This product is hygroscopic (moisture-sensitive). Protect from freezing and extreme heat. Under recommended storage conditions, the product is typically stable for 12 months from the date of manufacture. Keep away from strong oxidizing agents.
