Description

Hexanedioic Acid, Polymer With 1,3-Diisocyanatomethylbenzene, Methyloxirane And Oxirane is a specialized polyurethane-polyether hybrid polymer, also known as an adipic acid-based polyurethane prepolymer. This compound matters for its unique combination of properties derived from its segmented structure, offering excellent flexibility, adhesion, and chemical resistance. It is primarily needed by formulators in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as by manufacturers of high-performance composites and specialty resins.

Application

• High-Performance Coatings: Used as a key resin component in durable protective coatings for industrial equipment, automotive parts, and marine applications.
• Advanced Adhesives & Sealants: Serves as a base polymer for formulating strong, flexible structural adhesives and weather-resistant sealants.
• Elastomer Production: Acts as a prepolymer in the manufacture of castable polyurethane elastomers for gaskets, rollers, and impact-absorbing components.
• Composite Materials: Utilized as a matrix resin or modifier in fiber-reinforced plastics (FRP) and other composite systems to enhance toughness and interfacial bonding.
• Specialty Resins for Encapsulation: Employed in potting and encapsulation compounds to protect sensitive electronic components from moisture and mechanical stress.
• Textile & Leather Finishing: Functions as a coating or finishing agent to provide water repellency, abrasion resistance, and a soft hand feel.

Quality Control

Our production of this polymer adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as NCO content, hydroxyl value, viscosity, and residual monomer levels are rigorously monitored. A comprehensive Certificate of Analysis (COA) detailing all relevant specifications is provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a recommended temperature of 15-25°C (59-77°F). Keep away from heat, open flames, and sources of ignition. Moisture-sensitive; ensure containers are sealed when not in use to prevent absorption of atmospheric moisture which can affect product performance.
