Description

1,3-Benzenedicarboxylic acid, polymer with 1,3-bis(isocyanatomethyl)cyclohexane, 2,2-dimethyl-1,3-propanediol, 2-ethyl-2-(hydroxymethyl)-1,3-propanediol, hexanedioic acid and 1,6-hexanediol CAS NO 862074-39-3 is a high-performance, multi-component polyester-polyurethane copolymer. This engineered polymer is valued for its excellent balance of mechanical strength, chemical resistance, and thermal stability. It is primarily sought after by manufacturers in the coatings, adhesives, and specialty plastics industries who require durable, high-performance polymeric materials for demanding applications.

Application

• High-Performance Industrial Coatings: Used as a resin binder in protective coatings for metal, concrete, and plastic substrates, offering superior weatherability and chemical resistance.
• Advanced Adhesives and Sealants: Serves as a key component in structural adhesives and elastomeric sealants requiring strong bonding and flexibility.
• Engineering Thermoplastics and Composites: Incorporated into polymer blends and composite materials to enhance impact resistance, dimensional stability, and load-bearing capacity.
• Automotive and Aerospace Components: Utilized in under-the-hood parts, interior trim, and composite panels where durability under thermal and mechanical stress is critical.
• Wire and Cable Insulation: Applied as a protective jacketing material due to its good insulating properties and resistance to environmental degradation.
• Textile and Leather Finishing: Acts as a durable topcoat or finishing agent to improve abrasion resistance and longevity of treated fabrics and leathers.

Quality Control

Our production of this specialty copolymer adheres to strict quality management systems. Each batch is characterized for critical parameters including viscosity, hydroxyl value, acid number, and thermal properties to ensure consistent performance and batch-to-batch reproducibility. Certificates of Analysis (COA) detailing these specifications are available upon request. We support compliance with relevant global regulatory frameworks for industrial polymers.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (typically 15-25°C). Keep away from sources of heat, sparks, and open flame. As a polymeric material, it should be protected from prolonged exposure to high humidity to prevent potential moisture absorption which may affect processing characteristics.
