Description

Polydiethyleneglycol Adipate/Ipdi Copolymer is a specialized polyurethane prepolymer synthesized from adipic acid, diethylene glycol, and isophorone diisocyanate (IPDI). This compound matters for its excellent balance of flexibility, hydrolytic stability, and adhesion properties, making it a critical intermediate for high-performance materials. It is primarily needed by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries seeking to enhance product durability and performance under demanding conditions.

Application

• High-Performance Polyurethane Coatings: Used as a key resin component in two-component (2K) polyurethane coatings for industrial, automotive, and marine applications, providing excellent gloss retention and chemical resistance.
• Flexible Adhesives & Sealants: Serves as a prepolymer in the formulation of flexible, moisture-curing adhesives and sealants with strong substrate adhesion and good elongation.
• Elastomer Manufacturing: Acts as a building block for castable polyurethane elastomers used in rollers, wheels, and industrial parts requiring a combination of toughness and flexibility.
• Textile & Leather Finishing: Employed in coatings and binders for textiles and synthetic leather to impart softness, durability, and water resistance.
• Composite Materials: Utilized as a matrix resin or modifier in composite materials to improve impact resistance and interfacial bonding.
• Encapsulation & Potting Compounds: Formulated into systems for encapsulating and protecting sensitive electronic components from moisture and mechanical stress.

Quality Control

Our Polydiethyleneglycol Adipate/Ipdi Copolymer undergoes rigorous quality testing to ensure batch-to-batch consistency and compliance with industry standards. Key parameters such as NCO content, viscosity, hydroxyl value, and acid number are strictly monitored. Certificates of Analysis (COA) documenting these 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 nature, prolonged exposure to atmospheric humidity must be avoided to prevent premature reaction and viscosity increase. Keep away from heat sources and incompatible materials such as strong bases, acids, and oxidizing agents.
