Description

2-Oxepanone, polymer with 4-amino-α,α,4- trimethylcyclohexanemethanamine, 1,6-hexanediol, 2,2'-iminobis[ethanol], 1,1'-methylenebis[4-isocyanatocyclohexane] and 2,2'-oxybis[ethanol] is a specialized polyurethane or polyurethane-urea copolymer, synthesized from a precise blend of caprolactone, amines, diols, and diisocyanates. This engineered polymer is valued for its exceptional balance of flexibility, toughness, and chemical resistance, making it a critical performance additive in advanced material formulations. It is primarily sought by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries for developing high-performance, durable products. The compound, identified as CAS 68052-62-0, represents a key building block for creating materials that must withstand demanding environmental and mechanical stress.

Application

• High-Performance Coatings: Used as a resin modifier in industrial, automotive, and protective coatings to enhance flexibility, adhesion, and chemical resistance.
• Advanced Adhesives & Sealants: Serves as a key component in formulating structural adhesives and flexible sealants with superior bonding strength and durability.
• Specialty Elastomers: Incorporated into polyurethane elastomers for applications requiring a combination of toughness, abrasion resistance, and low-temperature performance.
• Composite Materials: Acts as a matrix resin or toughening agent in fiber-reinforced composites for the aerospace and automotive sectors.
• Textile & Leather Finishes: Utilized in coatings for textiles and synthetic leather to provide water resistance, flexibility, and a soft hand feel.
• Industrial Rollers & Gaskets: A raw material for manufacturing durable rollers, gaskets, and other molded polyurethane parts.

Quality Control

Every batch of our polyurethane copolymer is produced under a strict quality management system. We perform rigorous in-process and final testing to ensure consistent performance, including analysis of NCO content, viscosity, hydroxyl value, and molecular weight distribution. Certificates of Analysis (COA) detailing these specifications are provided with each shipment. Our production adheres to ISO 9001 standards, and we can support compliance with relevant regulatory frameworks such as REACH.

Storage

Preserve in a tightly closed, moisture-proof container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 15°C and 25°C (59°F and 77°F). Keep away from heat, open flames, and sources of ignition. Under these conditions, the product is typically stable for 12-24 months from the date of manufacture. Always check the specific label or technical data sheet for the recommended shelf life.
