Description

2-Propanol Acid, 1,1'-(Methylimino)Bis-, Polymer With 1,1-Methylene-Bis(4-Isocyanatocyclohexane) is a specialized polyurethane prepolymer or resin intermediate derived from a cycloaliphatic diisocyanate. This compound matters for its role in formulating high-performance, light-stable polyurethane systems with enhanced weatherability and mechanical properties. Manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries require this material to produce advanced polyurethane products that resist yellowing and degradation from UV exposure.

Application

• High-Performance Coatings: As a key component in automotive clear coats, industrial maintenance paints, and exterior architectural coatings where gloss retention and non-yellowing properties are critical.
• Advanced Adhesives & Sealants: Used in formulating structural adhesives for aerospace, automotive, and construction applications that demand durability and resistance to environmental factors.
• Specialty Elastomers: Serves as a precursor for cast, thermoplastic, or millable polyurethane elastomers used in rollers, gaskets, and demanding mechanical parts.
• UV-Stable Resins: Incorporated into resin systems for composites, encapsulants, and potting compounds that require long-term stability under sunlight.
• Industrial Finishes: For wood, plastic, and metal finishes that require a tough, flexible, and chemically resistant protective layer.

Quality Control

Our production of this polyurethane intermediate adheres to strict quality management systems. Every batch is characterized for critical parameters including NCO content, viscosity, and color to ensure consistency and performance in downstream formulations. Certificates of Analysis (COA) documenting full specifications are provided with each shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed, moisture-proof container, protected from light. Store in a cool, dry, and well-ventilated area. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F). Keep away from heat, open flames, and sources of ignition. Isolate from strong bases, amines, alcohols, and moisture to prevent premature reaction.
