Description

2-Oxepanone,Polymer With 1,1'-Methylenebis[4-Isocyanatocyclohexane] And 2,2'-Oxybis[Ethanol],2-Hydroxyethyl Acrylate-Blocked is a specialized, blocked polyurethane prepolymer designed for advanced coating and adhesive formulations. This compound matters for its ability to provide controlled reactivity, enabling the formulation of stable, one-component systems that cure upon exposure to heat to form durable, high-performance networks. Industries such as automotive, industrial maintenance coatings, and electronics encapsulation need this product to achieve excellent chemical resistance, adhesion, and flexibility in their final products.

Application

• Heat-Curable Industrial Coatings: As a key resin component in one-pack (1K) protective coatings for metal substrates, offering excellent corrosion and chemical resistance.
• Automotive Refinish and OEM Coatings: Used in primer-surfacers and clear coats where controlled cure profiles and superior finish are required.
• High-Performance Adhesives and Sealants: For formulating pre-mixed, moisture-stable adhesives that cure at elevated temperatures for bonding composites, plastics, and metals.
• Wire and Cable Enamels: Provides electrical insulation properties and thermal stability in magnet wire coatings.
• Flexible and Rigid Substrate Coatings: Applied on plastics, wood, and concrete to enhance durability and weatherability.
• Powder Coating Modifiers: Acts as a crosslinker or flow modifier in hybrid powder coating systems to improve film properties.

Quality Control

Our blocked polyurethane prepolymers undergo rigorous quality testing to ensure batch-to-batch consistency and performance reliability. Quality is monitored through parameters including blocked isocyanate content, viscosity, solids content, color, and cure characteristics. Certificates of Analysis (COA) detailing these specifications are available upon request. Our manufacturing processes adhere to ISO 9001 quality management standards, ensuring traceability and compliance for global industrial applications.

Storage

Preserve in a tightly closed 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 strong acids and organic solvents. Under these conditions, the product has a typical shelf life of 12 months from the date of manufacture. Do not freeze.
