Description

Hexanedioic Acid, Polymer With 1,3-Diisocyanato-2-Methylbenzene, 2,4-Diisocyanato-1-Methylbenzene, 1,2-Ethanediol And 2,2'-Oxybis[Ethanol] CAS NO 67815-75-2 is a specialized polyurethane prepolymer or resin intermediate synthesized from adipic acid, a mixture of toluene diisocyanate (TDI) isomers, and glycol chain extenders. This engineered polymer is valued for its ability to impart enhanced flexibility, chemical resistance, and durable mechanical properties to final cured materials. It is primarily sought by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as by producers of specialty polyurethane dispersions (PUDs) for high-performance applications.

Application

• High-Performance Coatings: Used as a key resin component in two-component polyurethane coatings for industrial maintenance, automotive refinish, and plastic substrates, providing excellent gloss, chemical resistance, and weatherability.
• Adhesives & Sealants: Serves as a prepolymer base for formulating flexible, high-strength polyurethane adhesives and sealants used in construction, automotive assembly, and footwear manufacturing.
• Elastomers and Castables: Employed in the production of cast polyurethane elastomers for industrial wheels, rollers, gaskets, and impact-absorbing components requiring a balance of toughness and elasticity.
• Polyurethane Dispersions (PUDs): Acts as a core intermediate for synthesizing waterborne polyurethane dispersions used in eco-friendly leather finishing, textile coatings, and wood finishes.
• Binder Systems: Utilized as a polymeric binder in composite materials, foundry sand binders, and specialty encapsulants.
• Fiber and Fabric Treatment: Imparts durable water repellency (DWR), softness, and abrasion resistance to technical textiles and non-wovens.

Quality Control

Our production of this polyurethane polymer intermediate adheres to strict batch-to-batch consistency protocols. Quality is monitored through key parameters including NCO content, viscosity, hydroxyl value, acid value, and color (APHA/Gardner). A comprehensive Certificate of Analysis (COA) detailing these specifications is provided with each shipment to ensure it meets your formulation requirements. We operate under a ISO 9001 quality management system, and our products are manufactured in compliance with relevant global regulatory frameworks.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (typically 15-25°C). Keep away from heat, sparks, and open flame. Moisture-sensitive; ensure containers are sealed to prevent absorption of atmospheric moisture which can lead to pre-reaction and viscosity increase. Separate from strong oxidizers, acids, bases, and amines.
