Description

2-Oxepanone, polymer with 2-aminoethanol, 5-amino-1,3,3-trimethylcyclohexanemethanamine, 2-ethyl-2-(hydroxymethyl)-1,3-propanediol, 1,1'-methylenebis[4-isocyanatocyclohexane] and 2,2'-oxybis[ethanol] is a specialized polyurethane or polyurethane-urea copolymer designed for high-performance applications. This engineered polymer offers a unique balance of properties derived from its multi-component structure, including toughness, chemical resistance, and tailored reactivity. It is essential for formulators and manufacturers in the coatings, adhesives, and advanced materials sectors seeking to develop products with enhanced durability and specific functional characteristics.

Application

• High-Performance Coatings: Used as a resin component in industrial, automotive, and protective coatings requiring excellent abrasion resistance, gloss, and weatherability.
• Advanced Adhesives & Sealants: Serves as a key polymer backbone in formulations for structural adhesives, flexible sealants, and bonding agents where strong adhesion and elasticity are critical.
• Elastomers and Castable Urethanes: Employed in the production of specialty polyurethane elastomers for gaskets, rollers, and impact-absorbing components.
• Composite Materials: Acts as a matrix resin or modifier in fiber-reinforced composites, enhancing interfacial bonding and mechanical properties.
• Industrial Fabric Finishes: Utilized in coatings for textiles, leather, and non-wovens to impart water resistance, durability, and a soft hand feel.
• Specialty Ink Resins: Incorporated into ink formulations for plastics and metals to improve adhesion, flexibility, and chemical resistance.

Quality Control

Our production of this advanced polymer adheres to strict quality management systems. Each batch is characterized for critical parameters including viscosity, hydroxyl value, isocyanate content (if applicable), and solid content to ensure batch-to-batch consistency. Certificates of Analysis (COA) detailing these specifications are available upon request. We support compliance with relevant global regulatory frameworks for industrial chemicals.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from heat, sparks, and open flame. This material is moisture-sensitive; ensure containers are sealed when not in use to prevent absorption of atmospheric moisture which may affect product performance.
