Description

2-Oxepanone, Polymer With 5-Amino-1,3,3-Trimethylcyclohexanemethanamine, 1,3-Diisocyanatomethylbenzene And α-Hydro-ω-Hydroxypoly( Oxy-1,2-Ethanediyl) is a specialized polyurethane-polyester hybrid polymer designed for high-performance applications. This compound matters because it combines the chemical resistance and durability of polyurethanes with the flexibility and adhesion properties of polyesters, creating a versatile material platform. It is primarily needed by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries seeking advanced material properties.

Application

• High-Performance Coatings: Used as a binder in industrial and protective coatings requiring excellent weatherability, chemical resistance, and mechanical strength.
• Advanced Adhesives & Sealants: Serves as a key component in formulating structural adhesives and flexible sealants with strong substrate adhesion and durability.
• Specialty Elastomers: Employed in the production of cast or molded polyurethane elastomers for gaskets, rollers, and industrial parts.
• Composite Materials: Acts as a matrix resin or modifier in fiber-reinforced composites to enhance toughness and interlayer bonding.
• Textile & Leather Finishing: Utilized in coatings for textiles and synthetic leather to provide a soft handle, abrasion resistance, and water repellency.
• Automotive & Aerospace Interiors: Applied in interior coatings and composite panels where a balance of lightweight properties and durability is critical.

Quality Control

Our production of this advanced polymer adheres to rigorous quality testing protocols to ensure batch-to-batch consistency and performance reliability. While specifications vary by intended application grade, our standard quality commitment includes verification of key parameters such as viscosity, hydroxyl value, isocyanate content, and thermal stability. Certificates of Analysis (COA) documenting these and other relevant tests are available upon request to support your quality assurance and regulatory compliance needs.

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). This material is moisture-sensitive; keep containers tightly sealed to prevent absorption of atmospheric moisture, which can affect product performance. Separate from strong oxidizing agents.
