Description

1,4-Cyclohexanedimethanol Polymer With 1,1′-Methylenebis[Isocyanatoben Zene] CAS NO 152187-59-2 is a high-performance polyurethane polymer derived from the reaction of 1,4-cyclohexanedimethanol (CHDM) and methylene diphenyl diisocyanate (MDI). This material is engineered to deliver exceptional durability, chemical resistance, and thermal stability, making it a critical component for demanding industrial applications. It is primarily utilized by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as in advanced composite materials.

Application

• High-Performance Coatings and Paints: Used as a binder in industrial, automotive, and marine coatings for superior gloss retention, weatherability, and chemical resistance.
• Advanced Adhesives and Sealants: Serves as a key polymer in structural adhesives and flexible sealants requiring strong bonding and long-term durability.
• Elastomers and Thermoplastic Polyurethanes (TPU): A fundamental raw material for producing flexible, abrasion-resistant elastomers used in wheels, gaskets, and industrial belts.
• Composite Materials: Incorporated into resin matrices for fiber-reinforced composites in automotive, aerospace, and construction applications.
• Industrial Rollers and Castings: Used in formulations for manufacturing durable rollers, industrial cast parts, and impact-resistant components.
• Encapsulants and Potting Compounds: Provides protective encapsulation for electronic components due to its good electrical properties and environmental shielding.

Quality Control

Our 1,4-Cyclohexanedimethanol Polymer With 1,1′-Methylenebis[Isocyanatoben Zene] is manufactured under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure consistent performance characteristics such as NCO content, viscosity, and molecular weight distribution. Certificates of Analysis (COA) documenting full specifications are provided with every shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed, moisture-proof container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from heat, open flames, and sources of ignition. Due to its reactivity with moisture, the container must be kept sealed under a dry atmosphere (e.g., nitrogen) after initial opening to prevent premature curing or gelation.
