Description

Hexanedioic acid, polymer with 5-amino-1,3,3-trimethylcyclohexanemethanamine, 2,2-dimethyl-1,3-propanediol, 1,6-hexanediol and 1,1'-methylenebis[4-isocyanatocyclohexane] is a high-performance, aliphatic polyurethane prepolymer or resin. This specialized polymer is engineered to deliver exceptional durability, chemical resistance, and weatherability, making it a critical component in demanding industrial applications. It is primarily sought by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries for formulating premium-grade products.

Application

• High-Performance Coatings: Used as a binder in automotive clear coats, industrial maintenance paints, and marine coatings where superior gloss retention, flexibility, and resistance to yellowing are required.
• Advanced Adhesives & Sealants: Serves as a key raw material for formulating structural adhesives, potting compounds, and elastic sealants with excellent bonding strength and environmental stability.
• Specialty Elastomers: Employed in the production of cast polyurethane elastomers for rollers, wheels, and industrial parts that demand high abrasion resistance and dynamic performance.
• Weatherable Films & Layers: Utilized in protective films, graphic arts, and composite layers that must withstand prolonged exposure to UV light and harsh outdoor conditions.
• Fiber & Textile Coatings: Applied as a coating or sizing agent to enhance the durability, water repellency, and feel of technical textiles and synthetic fibers.

Quality Control

Our production of this polyurethane polymer adheres to strict quality management systems. Every batch is characterized for critical parameters including NCO content, viscosity, solids content, and color to ensure consistency and performance. Certificates of Analysis (COA) documenting these specifications are available upon request, providing full traceability and compliance data for your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is moisture-sensitive (hygroscopic). Keep the container tightly sealed when not in use to prevent moisture absorption and contamination. Keep away from heat and incompatible materials such as strong acids, bases, and oxidizing agents.
