Description

Dibutylhexyl Ipdi CAS NO 185568-16-5 is a specialized aliphatic isocyanate derivative, specifically a diisocyanate, known for its role as a key building block in high-performance polymer synthesis. This compound is valued for its ability to impart excellent light stability, chemical resistance, and mechanical properties to final materials. It is primarily sought after by formulators and manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as in advanced polyurethane and polyurea applications.

Application

• High-Performance Polyurethane Coatings: Used as a crosslinker in automotive clear coats, industrial finishes, and coil coatings requiring superior weatherability and yellowing resistance.
• Specialty Adhesives & Sealants: Serves as a core component in formulating prepolymers for structural adhesives, flexible sealants, and potting compounds with enhanced durability.
• Elastomer Production: A critical raw material for manufacturing cast, thermoplastic, and millable polyurethane elastomers used in wheels, rollers, and gaskets.
• Polyurea Spray Systems: Employed in fast-curing, abrasion-resistant polyurea linings for tanks, truck beds, and industrial flooring.
• UV-Stable Resins: Incorporated into resin systems for outdoor applications where long-term color and gloss retention are critical.
• Chemical Intermediate: Used in organic synthesis to create other specialty chemicals, including chain extenders and blocked isocyanates.

Quality Control

Our Dibutylhexyl Ipdi is produced under stringent quality management systems to ensure batch-to-batch consistency and high purity. Quality is verified through a comprehensive suite of analytical tests including gas chromatography (GC) and titration methods. A Certificate of Analysis (COA) detailing purity, isocyanate content, and impurity profiles is provided with every shipment to support your quality assurance protocols.

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). This product is hygroscopic (moisture-sensitive) and must be kept under a dry inert atmosphere (e.g., nitrogen) to prevent reaction with atmospheric moisture. Keep away from heat, sparks, and open flame.
