Description

Hexanedioic Acid, Polymer With 1,4-Butanediol, 1,3-Diisocyanato-2-Methylbenzene And 2,4-Diisocyanato-1-Methylbenzene CAS NO 96446-47-8 is a high-performance polyurethane prepolymer or resin derived from adipic acid, butanediol, and a mixture of toluene diisocyanate (TDI) isomers. This specialized polymer is engineered to deliver exceptional durability, flexibility, and chemical resistance in demanding industrial formulations. It is a critical raw material for manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries seeking to enhance product performance.

Application

• High-Performance Coatings: Used as a binder in industrial and protective coatings for metal, concrete, and plastic substrates, providing excellent abrasion and chemical resistance.
• Adhesives & Sealants: Serves as a key component in formulating structural adhesives, potting compounds, and flexible sealants with strong bonding strength and environmental stability.
• Elastomers and Castables: A precursor for manufacturing polyurethane elastomers, gaskets, rollers, and impact-absorbing components.
• Composite Materials: Used in the production of fiber-reinforced plastics and composite materials to improve matrix toughness and interfacial adhesion.
• Textile & Leather Finishing: Applied in coatings and finishes to impart water repellency, durability, and a soft hand feel to fabrics and leather goods.
• Automotive Components: Found in under-the-hood parts, interior trim, and vibration-damping materials due to its thermal and mechanical properties.

Quality Control

Our production of this polyurethane polymer adheres to strict quality management systems. Each batch is characterized for critical parameters including NCO content, viscosity, and hydroxyl value to ensure consistency and performance. Certificates of Analysis (COA) detailing these specifications are provided with every shipment to guarantee compliance with your formulation requirements.

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 moisture-sensitive (hygroscopic) and may react with water; ensure containers are sealed when not in use to prevent moisture absorption and premature curing. Keep away from heat sources and open flames.
