Description

1,3-Benzenedicarboxylic acid, polymer with 5-amino-1,3,3-trimethylcyclohexanemethanamine, 2,2-dimethyl-1,3-propanediol, hexanedioic acid, 1,6-hexanediol, 3-hydroxy-2-(hydroxymethyl)-2-methylpropanoic acid and 1,1-methylenebis4-isocyanatocyclohexane is a high-performance, multi-component polyurethane or polyurethane-urea copolymer. This engineered polymer is valued for its excellent mechanical properties, chemical resistance, and thermal stability, making it suitable for demanding industrial applications. It is primarily sought by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) sectors, as well as for advanced composite materials.

Application

• High-Performance Coatings: Used in formulating durable industrial, automotive, and protective coatings that require exceptional abrasion resistance and weatherability.
• Advanced Adhesives & Sealants: Serves as a key component in structural adhesives and high-strength sealants for aerospace, automotive, and construction applications.
• Engineering Elastomers: Employed in the production of castable polyurethane elastomers for rollers, wheels, gaskets, and other mechanical parts.
• Composite Materials: Acts as a matrix resin or binder in fiber-reinforced composites for lightweight, high-strength components.
• Specialty Films & Membranes: Utilized to create films with specific barrier properties, flexibility, and toughness.
• Industrial Binders: Functions as a robust binder in abrasive tools, friction materials, and other consolidated products.

Quality Control

Our production of this specialty polymer adheres to strict quality management systems. Each batch is characterized for critical parameters including viscosity, solids content, isocyanate (NCO) content (if applicable), and mechanical property profiles to ensure consistent performance and batch-to-batch reproducibility. A comprehensive Certificate of Analysis (COA) detailing all relevant specifications is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive). Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep the container tightly sealed under a dry, inert atmosphere (e.g., nitrogen blanket) to prevent moisture absorption and premature polymerization or gelation.
