Description

1,2-Benzenedicarboxylic Acid, Polymer With Hexanedioic Acid, 1,1-Methylenebis4-Isocyanatobenzene And 2,2-Oxybisethanol CAS NO 261164-44-7 is a specialized polyurethane-polyester copolymer designed for high-performance applications. This engineered polymer offers a unique balance of chemical resistance, mechanical strength, and thermal stability derived from its composite structure. It is essential for manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries seeking durable and reliable polymeric materials.

Application

• High-Performance Industrial Coatings: Used as a resin binder in protective coatings for metal, concrete, and plastic substrates, providing excellent weatherability and chemical resistance.
• Specialty Adhesives and Sealants: Serves as a key polymeric component in formulations requiring strong bonding, flexibility, and durability under harsh environmental conditions.
• Elastomer and Rubber Modification: Employed to enhance the properties of polyurethane elastomers, improving tear strength, abrasion resistance, and load-bearing capacity.
• Composite Materials: Acts as a matrix or modifier in fiber-reinforced plastics (FRP) and other composite systems to improve interfacial adhesion and mechanical performance.
• Automotive and Aerospace Components: Utilized in under-the-hood parts, interior panels, and structural components where a combination of lightweight and high strength is critical.
• Wire and Cable Insulation: Formulated into jacketing materials that require good insulation properties, flame retardancy, and resistance to oils and solvents.

Quality Control

Our production of this advanced copolymer adheres to rigorous quality management systems. Each batch is characterized for critical parameters including molecular weight distribution, viscosity, hydroxyl value, and isocyanate content to ensure batch-to-batch consistency and performance reliability. Certificates of Analysis (COA) documenting full specifications are available upon request, supporting compliance in regulated supply chains.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (typically 15-25°C). Keep away from heat, sparks, and open flame. This material is moisture-sensitive; ensure containers are sealed to prevent absorption of atmospheric moisture which can affect product properties.
