Description

Fatty acids, C18-unsatd., dimers, di-Me esters, hydrogenated polymers with adipic acid, 5-amino-1,3,3-trimethylcyclohexanemethanamine, 5-isocyanato-1-(isocyanatomethyl)-1,3,3-trimethylcyclohexane and 3-methyl-1,5-pentanediol CAS NO 252046-77-8 is a specialized, high-performance polymer intermediate designed for demanding industrial applications. This complex, multi-component compound offers a unique combination of flexibility, reactivity, and durability derived from its hybrid structure of dimerized fatty acid esters, aliphatic/cycloaliphatic amines, isocyanates, and diols. It is engineered for manufacturers seeking to enhance the mechanical properties and chemical resistance of their final polymeric products. This material is particularly valuable in the formulation of advanced coatings, adhesives, and elastomers where superior performance is critical.

Application

• High-Performance Polyurethane Coatings: Serves as a key building block for polyurethane resins used in industrial, automotive, and marine coatings, providing excellent weatherability, chemical resistance, and mechanical strength.
• Specialty Adhesives and Sealants: Used in formulating structural and elastic adhesives, offering strong bonding, flexibility, and durability under stress and environmental exposure.
• Advanced Elastomers: A critical component in the synthesis of polyurethane and polyurea elastomers for applications requiring high abrasion resistance, tensile strength, and dynamic performance.
• Composite Materials: Acts as a modifier or cross-linking agent in polymer composites to improve impact resistance, adhesion between phases, and overall material toughness.
• Industrial Resins and Binders: Employed in the production of binders for foundry sands, abrasives, and non-woven materials, leveraging its strong adhesive and film-forming properties.
• Flexible Foams and Cushioning Materials: Can be utilized to tailor the flexibility and resilience of polyurethane foams for specialized cushioning applications.

Quality Control

Our production of this advanced polymer intermediate adheres to strict quality management protocols to ensure batch-to-batch consistency and performance reliability. Key parameters such as isocyanate (NCO) content, amine value, viscosity, and color are rigorously monitored using standardized analytical methods including titration, viscometry, and spectrophotometry. A comprehensive Certificate of Analysis (COA) detailing all relevant specifications is provided with each shipment to support your quality assurance processes.

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., under dry nitrogen) to prevent premature reaction or degradation. Recommended storage temperature is between 15°C and 25°C in a cool, dry, well-ventilated area away from heat sources and incompatible materials such as water, alcohols, amines, and strong acids/bases.
