Description

2-Oxepanone polymer with 5-amino-1,3,3-trimethylcyclohexanemethanamine, α-hydro-ω-hydroxypoly(oxy-1,2-ethanediyl), 4,4'-methylenebis[cyclohexanamine] and 1,1'-methylene bis[4-isocyanatocyclohexane] is a high-performance, multi-component polymer designed for advanced material applications. This specialized compound is engineered to deliver exceptional durability, chemical resistance, and tailored mechanical properties, making it a critical component for demanding industrial formulations. It is primarily utilized by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as in the production of specialty composites and high-performance resins.

Application

• High-Performance Coatings and Paints: Used as a key resin component in industrial, automotive, and marine coatings for enhanced weatherability, gloss retention, and chemical resistance.
• Advanced Adhesives and Sealants: Serves as a base polymer for structural adhesives, potting compounds, and flexible sealants requiring strong bonding and environmental stability.
• Specialty Elastomers and Urethane Systems: A vital ingredient in the formulation of polyurethane elastomers, offering excellent tensile strength, abrasion resistance, and low-temperature flexibility.
• Composite Materials: Employed as a matrix resin or modifier in fiber-reinforced plastics (FRP) and other composite systems to improve impact resistance and interfacial adhesion.
• Industrial and Protective Linings: Formulated into linings for tanks, pipes, and flooring that require robust protection against corrosive chemicals and mechanical wear.
• Electrical Encapsulation: Used in potting and encapsulation compounds for electronic components, providing excellent insulation and protection from moisture and vibration.

Quality Control

Our production of this advanced polymer adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Each lot undergoes comprehensive analytical testing, including assessment of key parameters such as viscosity, isocyanate (NCO) content, hydroxyl value, and molecular weight distribution. Certificates of Analysis (COA) documenting all test results are provided with every shipment. We support compliance with relevant global regulatory frameworks, including REACH, and can tailor specifications to meet specific customer or application standards.

Storage

Preserve in a tightly closed container, protected from light. This product is hygroscopic (moisture-sensitive) and must be stored under a dry, inert atmosphere (e.g., nitrogen blanket) to prevent degradation. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F) in a cool, dry, well-ventilated area away from heat sources and incompatible materials. Keep containers sealed when not in use.
