Description

2H-Azepin-2-one, hexahydro-, polymer with 2-ethyl-2-(hydroxymethyl)-1,3-propanediol, 5-isocyanato-1-(isocyanatomethyl)-1,3,3-trimethylcyclohexane and 2,2'-oxybis[ethanol] CAS NO 75790-76-0 is a specialized polyurethane prepolymer or resin intermediate, engineered for high-performance applications. This compound is valued for its ability to impart enhanced durability, chemical resistance, and tailored mechanical properties to final polymeric materials. It is primarily sought by formulators and manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as in advanced composite production.

Application

• High-Performance Coatings: Used as a key resin component in industrial, automotive, and protective coatings requiring excellent weatherability and chemical resistance.
• Specialty Adhesives & Sealants: Serves as a building block for formulating polyurethane-based adhesives and sealants with strong bonding strength and flexibility.
• Elastomer Production: Employed in the synthesis of castable or thermoplastic polyurethane elastomers for gaskets, wheels, and industrial parts.
• Composite Materials: Acts as a matrix resin or modifier in fiber-reinforced composites for the aerospace, marine, and automotive sectors.
• Encapsulation & Potting Compounds: Utilized in electronic and electrical applications for protective encapsulation due to its insulating and adhesive properties.
• Industrial Binders: Functions as a reactive binder in foundry sands, abrasives, and other composite systems.

Quality Control

Our production of this polymer intermediate 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 color are rigorously monitored. A comprehensive Certificate of Analysis (COA) detailing all relevant specifications is provided with each shipment to support your quality assurance processes.

Storage

Preserve in a tightly closed, moisture-proof container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures recommended for polyurethane precursors, typically between 15°C and 25°C (59°F and 77°F). Keep away from heat, sparks, open flames, and incompatible materials such as strong bases, acids, and moisture. Under these conditions, the product is typically stable for the period indicated on the label.
