Description

Hexanedioic acid, polymer with 1,3-diisocyanatomethyl benzene, 1,2-ethanediol and 1,2-propanediol is a high-performance polyurethane prepolymer or resin intermediate, synthesized from adipic acid, ethylene glycol, propylene glycol, and toluene diisocyanate. This versatile polymer is valued for its ability to impart excellent flexibility, toughness, and chemical resistance to final cured materials. It is primarily sought after by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as for specialty composite and binder applications.

Application

• Flexible Coatings and Paints: Used as a key component in high-performance polyurethane coatings for automotive, industrial, and marine applications, providing durability and weatherability.
• Adhesives and Sealants: Serves as a base resin for formulating strong, flexible polyurethane adhesives and sealants used in construction, automotive assembly, and footwear manufacturing.
• Elastomers and Castable Urethanes: A fundamental building block for producing polyurethane elastomers with tailored hardness, rebound resilience, and abrasion resistance for wheels, rollers, and industrial parts.
• Composite Binders: Employed as a polymeric binder in composite materials, enhancing the bonding between fibers and matrices in lightweight structural components.
• Textile and Leather Finishes: Utilized in coatings for textiles and synthetic leather to improve water resistance, flexibility, and feel.
• Specialty Resin Modifications: Acts as a modifier for other resin systems to improve impact resistance, flexibility, and adhesion properties.

Quality Control

Our production of this polyurethane polymer adheres to strict quality management protocols to ensure batch-to-batch consistency and performance reliability. Key parameters such as NCO content, viscosity, hydroxyl value, and acid number are rigorously monitored. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with each shipment to support your quality assurance processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent moisture absorption, which can affect product performance. Keep away from heat, sparks, and open flame.
