Description

2H-Azepin-2-One, Hexahydro-, Polymer With 1,2-Ethanediol And 5-Isocyanato-1-(Isocyanatomethyl) -1,3,3-Trimethylcyclohexane is a high-performance polyurethane prepolymer derived from caprolactam, ethylene glycol, and isophorone diisocyanate (IPDI). This specialized polymer is engineered to deliver exceptional durability, chemical resistance, and tailored mechanical properties in demanding industrial applications. It is a critical raw material for manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries seeking to enhance product performance and longevity.

Application

• High-Performance Coatings & Paints: Used as a binder in industrial, automotive, and marine coatings for superior abrasion resistance, gloss retention, and weatherability.
• Advanced Adhesives & Sealants: Serves as a key component in formulating structural adhesives and flexible sealants with excellent bonding strength and environmental stability.
• Specialty Elastomers & Castables: Employed in the production of polyurethane elastomers for rollers, gaskets, and wear-resistant parts requiring a balance of hardness and elasticity.
• Composite Materials: Acts as a matrix resin or modifier in fiber-reinforced plastics (FRP) and other composites to improve impact resistance and interfacial adhesion.
• Waterproofing & Corrosion Protection: Formulated into protective linings, membranes, and anti-corrosive primers for infrastructure and industrial equipment.
• Textile & Leather Finishing: Provides durable, flexible coatings for synthetic leather, waterproof fabrics, and other technical textiles.

Quality Control

Our production of this polyurethane prepolymer adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as NCO content, viscosity, and color are rigorously monitored. A comprehensive Certificate of Analysis (COA) detailing purity, specifications, and test results is provided with every shipment 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 recommended for polyurethane prepolymers (typically 15-25°C). Keep away from heat, open flames, and sources of ignition. Due to the reactive isocyanate groups, protect from moisture and atmospheric humidity to prevent premature curing or gelation.
