Description

Hexanedioic Acid, Polymer With2,4-Diisocyanato-1-Methylbenzene And 1,2-Ethanediol CAS NO 28132-94-7 is a specialized polyurethane prepolymer or resin derived from adipic acid, toluene diisocyanate (TDI), and ethylene glycol. This engineered polymer is valued for its ability to impart specific mechanical properties, chemical resistance, and durability to final formulations. It is primarily utilized by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as in advanced material synthesis where tailored polymer performance is critical.

Application

• High-Performance Coatings and Paints: Serves as a key resin component in industrial, automotive, and protective coatings, enhancing gloss, hardness, and weatherability.
• Adhesives and Sealants: Used in formulating structural and flexible adhesives, including those for construction, automotive assembly, and footwear.
• Elastomers and Urethane Rubbers: Acts as a prepolymer for manufacturing castable, thermoplastic, or millable polyurethane elastomers with excellent abrasion resistance.
• Binder Systems: Employed as a polymeric binder in composite materials, foundry sand binders, and non-woven fiber applications.
• Textile and Leather Finishing: Provides durable, flexible finishes for synthetic leather, waterproof textiles, and fabric coatings.
• Specialty Material Modification: Used to modify the properties of other polymers or as an intermediate for further chemical synthesis.

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, hydroxyl value, viscosity, and acid number are rigorously monitored. A comprehensive Certificate of Analysis (COA) detailing the specific specifications for your ordered grade is provided with each shipment.

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). Due to its hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed to prevent moisture absorption, which can affect product performance. Keep away from heat sources and incompatible materials.
