Description

2-Oxepanone, polymer with N-(1,3-dimethylbutylidene)-N'-[2-[(1,3-dimethylbutylidene)amino]ethyl]-1,2-ethanediamine, 5-isocyanato-1-(isocyanatomethyl)-1,3,3-trimethylcyclohexane and 2,2'-oxybis[ethanol] is a specialized polyurethane prepolymer or polymer derived from ε-caprolactone, a diamine chain extender, isophorone diisocyanate (IPDI), and diethylene glycol. This engineered material matters for its ability to impart a unique balance of flexibility, chemical resistance, and durability to final formulations. It is primarily needed by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as for producing high-performance specialty polymers.

Application

• High-Performance Coatings: Used as a key resin component in industrial, automotive, and protective coatings requiring excellent weatherability, chemical resistance, and mechanical strength.
• Specialty Adhesives & Sealants: Serves as a base polymer for formulating flexible, durable adhesives and sealants with strong bonding properties and environmental stability.
• Elastomer Production: Acts as a prepolymer for manufacturing cast or thermoplastic polyurethane elastomers (TPU) used in gaskets, rollers, and impact-resistant parts.
• Composite Materials: Employed as a matrix resin or modifier in fiber-reinforced composites to enhance toughness and interfacial adhesion.
• Industrial Binders: Utilized in binder systems for advanced materials, including abrasives, nonwovens, and filtration media.
• Flexible Films & Coatings: Imparts flexibility and toughness to films and coatings for textiles, packaging, and flexible substrates.

Quality Control

Our production of this specialty polymer adheres to strict quality management protocols. Each batch undergoes rigorous analytical testing to ensure consistency in critical parameters such as NCO content, viscosity, solids content, and color. We provide comprehensive Certificates of Analysis (COA) with every shipment, detailing the specific results against agreed specifications. Our quality system is designed to support applications requiring reliable performance and batch-to-batch uniformity.

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/59-77°F). This product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent moisture ingress, which can affect product performance. Keep away from heat, sparks, and open flame.
