Description

Carbonic Acid, Polymer With 1,6-Hexane-Diol, 1,1'-Methylenebis[4-Isocyanato-Benzene] And 2,2'-[1,4-Phenylenebis(Oxy)Bis[Ethanol] is a specialized polyurethane or polycarbonate-based polymer, identified by CAS NO 89485-74-5. This engineered material is valued for its tailored balance of flexibility, chemical resistance, and durability, making it a critical component in high-performance applications. It is primarily sought by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as in advanced material science for creating specialized films and composites.

Application

• High-Performance Coatings and Paints: Used as a resin binder to formulate durable, chemical-resistant, and weatherable industrial and protective coatings.
• Advanced Adhesives and Sealants: Serves as a key polymer component in structural adhesives and flexible sealants requiring strong bonding and environmental stability.
• Specialty Elastomers and Urethane Rubbers: A precursor for manufacturing castable or thermoplastic polyurethane elastomers with specific mechanical properties.
• Composite Materials: Utilized in the matrix of fiber-reinforced composites for automotive, aerospace, or sporting goods applications.
• Film and Sheet Production: Employed in the creation of specialty films for packaging, laminates, or release layers.
• Industrial Gaskets and Molded Parts: Acts as a base material for producing custom-molded components that demand resilience and dimensional stability.

Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Quality is monitored through parameters such as viscosity, hydroxyl value, isocyanate content, and molecular weight distribution. Certificates of Analysis (COA) are available upon request, detailing batch-specific results. Production adheres to a Quality Management System, ensuring consistency and traceability for industrial and specialty chemical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (typically 15-25°C). This material is moisture-sensitive (hygroscopic); keep the container tightly sealed to prevent exposure to atmospheric humidity. Separate from strong acids, bases, and oxidizing agents.
