Description

Poly(Isophorone Diisocyanate) is a high-performance aliphatic diisocyanate monomer, also known by its CAS number 53880-05-0. It is a critical building block valued for its excellent light stability, chemical resistance, and mechanical properties in polymer synthesis. This product is essential for manufacturers in the coatings, adhesives, and specialty elastomers industries seeking durable, weatherable, and high-quality polyurethane formulations.

Application

• High-Performance Coatings: Used in the synthesis of polyurethane resins for automotive clear coats, industrial maintenance coatings, and coil coatings where superior UV resistance and color retention are required.
• Adhesives & Sealants: Serves as a key component in the production of light-stable, flexible, and durable polyurethane adhesives and sealants for construction and automotive assembly.
• Elastomers: A fundamental raw material for manufacturing aliphatic polyurethane elastomers used in applications demanding toughness and resistance to environmental degradation.
• UV-Curable Systems: Incorporated into oligomers and prepolymers for radiation-curable coatings and inks, contributing to fast curing and enhanced film properties.
• Waterborne Polyurethane Dispersions (PUDs): Used to create internally emulsified, aliphatic PUDs for eco-friendly coatings with excellent durability.
• Specialty Intermediates: Acts as a versatile intermediate for further chemical modification, enabling the creation of custom polymers with tailored properties.

Quality Control

Our Poly(Isophorone Diisocyanate) is manufactured under stringent quality management systems. Every batch undergoes comprehensive analytical testing, including determination of NCO content, viscosity, color, and monomer content, to ensure consistency and performance. Certificates of Analysis (COA) documenting full specifications are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed, moisture-proof 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). Due to its hygroscopic and moisture-sensitive nature, containers must be kept tightly sealed under a dry inert atmosphere (e.g., nitrogen) to prevent reaction with atmospheric moisture. Keep away from heat, open flames, and incompatible materials such as alcohols, amines, and water.
