Description

Hexanedioic Acid, Polymer With 1,6-Hexanediol And 1,1'-Methylenebis[Isocyanatobenzene] is a high-performance polyurethane prepolymer or polyurethane elastomer. This specialized polymer is engineered to deliver exceptional durability, chemical resistance, and mechanical strength in demanding formulations. It is a critical raw material for manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as for advanced material science applications requiring tailored polymer properties.

Application

• High-Performance Coatings & Paints: Used as a binder in industrial, automotive, and marine coatings for superior abrasion resistance, gloss, and weatherability.
• Adhesives & Sealants: Serves as a key component in structural adhesives, potting compounds, and flexible sealants requiring strong bonding and elasticity.
• Elastomers & Castable Urethanes: Formulated into rollers, wheels, gaskets, and impact-absorbing parts that demand high tensile strength and tear resistance.
• Composite Materials: Acts as a matrix resin or toughening agent in fiber-reinforced plastics and other composite systems.
• Textile & Leather Finishing: Imparts durable water repellency (DWR), softness, and wear resistance to fabrics and synthetic leather.
• Specialty Resins for 3D Printing: Utilized in advanced additive manufacturing processes to create robust, functional prototypes and end-use parts.

Quality Control

Our production of this polymer adheres to strict quality management systems. Each batch is characterized for critical parameters including NCO content, viscosity, hydroxyl value, and acid number to ensure consistent performance. Certificates of Analysis (COA) documenting full specifications are provided with every shipment. We support compliance with relevant 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 room temperature (15-25°C / 59-77°F). This material is moisture-sensitive (hygroscopic) and may react with water; ensure containers are sealed under a dry atmosphere (e.g., nitrogen) after opening. Keep away from heat, sparks, and open flame. Separate from strong acids, bases, and oxidizing agents.
