Description

Methylenedi-4,1-Cyclohexyleneisocyanate, 5-Amino-1,3,3-Trimethylcyclohexanemethanamine, 2-Oxepanone Polymer is a specialized polyurethane prepolymer based on a cycloaliphatic isocyanate and amine system, modified with a caprolactone segment. This engineered material is valued for its ability to impart enhanced weatherability, chemical resistance, and mechanical strength to final polyurethane products. It is primarily utilized in the formulation of high-performance coatings, adhesives, sealants, and elastomers for demanding industrial applications.

Application

• High-Performance Coatings: Used as a key component in polyurethane coatings for automotive, aerospace, and industrial maintenance, offering excellent UV stability and gloss retention.
• Advanced Adhesives & Sealants: Serves as a base polymer for structural adhesives and flexible sealants requiring strong bonding and durability under harsh environmental conditions.
• Specialty Elastomers: Formulated into cast or thermoplastic polyurethane elastomers for gaskets, rollers, and wear-resistant parts.
• Composite Materials: Acts as a matrix resin or binder in fiber-reinforced composites for the marine and construction sectors.
• Potting & Encapsulation: Employed for protecting sensitive electronic components due to its good adhesion and insulating properties.
• Waterborne Polyurethane Dispersions (PUDs): Can be modified for use in environmentally friendly coating and adhesive formulations.

Quality Control

Our production of this specialty polyurethane prepolymer adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing, including determination of NCO content, viscosity, and residual monomer levels, to ensure consistent performance and batch-to-batch reliability. A Certificate of Analysis (COA) detailing all relevant specifications is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. This product is hygroscopic (moisture-sensitive). Store in a cool, dry, and well-ventilated area at room temperature (typically 15-25°C). Keep the container tightly sealed under a dry inert atmosphere (e.g., nitrogen) to prevent moisture absorption and premature reaction. Observe all local regulations for chemical storage.
