Description

2-Oxepanone, homopolymer, ester with .alpha.-methyl-.omega.-hydroxypoly(oxy-1,2-ethanediyl), reaction products with N,N-dimethyl-1,3-propanediamine, polyethylene glycol mono-Me ether and poly-TDI is a specialized, multi-component polymeric material designed for advanced industrial applications. This product matters because it combines the properties of polycaprolactone, polyethers, and polyurethanes into a single, reactive polymer system, offering unique tunability for performance coatings, adhesives, and functional materials. Industries such as specialty coatings, advanced adhesives, and polymer modification require this material to develop products with enhanced flexibility, adhesion, and chemical resistance.

Application

• High-Performance Coatings: Used as a key resin component in durable, flexible, and chemically resistant industrial and protective coatings.
• Advanced Adhesives & Sealants: Serves as a polymeric backbone for formulating adhesives with excellent substrate wetting and bond strength.
• Polymer Modification & Additives: Acts as a compatibilizer or property enhancer in polymer blends and composites.
• Specialty Inks: Utilized in the formulation of inks requiring specific rheological and film-forming properties.
• Textile & Leather Finishes: Employed in coatings and finishes to impart softness, water resistance, and durability.
• Reactive Intermediate: Functions as a prepolymer for further chemical synthesis in custom polymer production.

Quality Control

Our production of this advanced polymer adheres to strict quality management systems. Each batch is characterized for critical parameters including hydroxyl value, isocyanate content (NCO%), viscosity, and molecular weight distribution to ensure consistency and performance. Certificates of Analysis (COA) detailing these specifications are provided with every shipment. 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). This material is moisture-sensitive; ensure containers are sealed after use to prevent absorption of atmospheric moisture, which can affect reactivity and properties. Keep away from heat sources and open flame.
