Description

1,3-Benzenedicarboxylic acid, 5-sulfo-, monosodium salt, polymer with 1,3-diisocyanatomethylbenzene, 1,2-ethanediol, 2-ethyl-2-(hydroxymethyl)-1,3-propanediol, hexanedioic acid, 2-hydroxyethyl 2-propenoate, 2-oxepanone and 2,2-oxybisethanol is a high-performance, water-dispersible polyurethane polymer designed for demanding industrial applications. This advanced copolymer integrates sulfonated aromatic units, polyols, and lactone segments to deliver exceptional film-forming, adhesion, and chemical resistance properties. It is a critical raw material for formulators in the coatings, adhesives, and specialty polymer industries seeking to enhance product durability and performance.

Application

• Waterborne Industrial Coatings: As a key film-forming resin for metal, plastic, and wood coatings requiring high gloss, hardness, and corrosion resistance.
• Adhesives and Sealants: Used in the formulation of high-strength, flexible adhesives for automotive, construction, and packaging applications.
• Textile and Leather Finishing: Provides durable, breathable, and soft-hand finishes for synthetic and natural fabrics and leather goods.
• Inkjet Receptive Coatings: Serves as a binder in coatings for premium photo papers and specialty printing media to enhance ink adhesion and color vibrancy.
• Fiber Sizing and Composite Binders: Improves the interfacial adhesion and processability of glass or carbon fibers in reinforced composite materials.
• Specialty Polymer Modifications: Employed as an additive to improve the toughness, weatherability, and dispersion characteristics of other polymer systems.

Quality Control

Our production of this advanced polymer adheres to strict quality management systems, ensuring batch-to-batch consistency for critical formulation parameters. Every lot is tested for key performance indicators including solids content, viscosity, pH, and particle size distribution. A comprehensive Certificate of Analysis (COA) detailing these specifications is provided with each shipment to support your quality assurance protocols.

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 and 77°F). This product is hygroscopic (moisture-sensitive). Protect from freezing and extreme heat to maintain product stability and prevent coagulation or changes in dispersion properties.
