Description

1,2-Ethanediol, Polymer With 2,4-Diisocyanato-1-Methylbenzene is a specialized polyurethane prepolymer or oligomer derived from the reaction of ethylene glycol and toluene diisocyanate (TDI). This compound matters as a crucial reactive intermediate, offering controlled molecular weight and isocyanate functionality for precise polymer synthesis. It is primarily needed by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as for producing tailored polyurethane resins, where it serves as a building block to impart specific flexibility, adhesion, and chemical resistance properties.

Application

• Polyurethane Resin Synthesis: A key prepolymer for manufacturing various polyurethane resins with tailored properties.
• High-Performance Coatings: Used in formulating durable industrial, automotive, and protective coatings that require excellent weatherability and chemical resistance.
• Adhesives & Sealants: Serves as a base component in polyurethane-based adhesives and sealants, providing strong bonding and flexibility.
• Elastomer Production: Employed in the creation of castable and thermoplastic polyurethane elastomers for gaskets, wheels, and industrial parts.
• Binder Systems: Utilized as a reactive binder in composite materials and foundry core binders.
• Textile & Leather Finishing: Acts as a component in finishes and coatings to enhance durability and water repellency.
• Specialty Polymer Modification: Used to modify other polymers, introducing urethane linkages to improve toughness and compatibility.

Quality Control

Our 1,2-Ethanediol, Polymer With 2,4-Diisocyanato-1-Methylbenzene is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing to ensure consistency in key parameters such as isocyanate (NCO) content, viscosity, and molecular weight distribution. Certificates of Analysis (COA) documenting purity and specifications are available upon request, supporting compliance with relevant industry standards for polymer intermediates.

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, the container must be kept tightly sealed to prevent moisture absorption, which can lead to premature reaction and gelation. Isolate from strong acids, bases, and sources of heat or ignition.
