Description

1,3-Benzenedicarboxylic acid polymer with 1,3-diisocyanatomethylbenzene, 2-ethyl-2-(hydroxymethyl)-1,3-propanediol, hexanedioic acid and α,α'-[(1-methylethylidene)di-4,1-phenylene]bis[ω-hydroxypoly[oxy(methyl-1,2-ethanediyl)]], benzoate is a high-performance, multi-component polymeric resin designed for demanding industrial applications. This compound, identified by CAS No. 174175-24-7, matters for its ability to provide a unique balance of chemical resistance, thermal stability, and mechanical properties derived from its complex polyurethane-polyester hybrid structure. It is primarily needed by formulators and manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries seeking advanced performance materials.

Application

• High-Performance Industrial Coatings: Used as a key resin in formulations for protective coatings requiring excellent weatherability, chemical resistance, and durability.
• Specialty Adhesives and Sealants: Serves as a base polymer for structural adhesives and flexible sealants where strong bonding and environmental resistance are critical.
• Elastomer and Composite Manufacturing: Employed in the production of cast elastomers, gaskets, and composite materials that demand a specific profile of toughness and flexibility.
• Automotive and Aerospace Components: Utilized in under-the-hood applications, interior trim adhesives, and composite parts requiring thermal and chemical stability.
• Electrical Encapsulation and Potting: Acts as a protective resin for electronic components, providing insulation and protection from moisture and vibration.
• Fiber and Fabric Coatings: Applied as a coating to textiles and industrial fibers to enhance water repellency, abrasion resistance, and durability.

Quality Control

Our production of this advanced polymer adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as viscosity, hydroxyl value, isocyanate content (if applicable), and solid content are rigorously monitored. A comprehensive Certificate of Analysis (COA) detailing specific test results is provided with each shipment to support your quality assurance and regulatory compliance needs.

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). Keep away from heat, sparks, and open flame. Containers should be kept tightly sealed when not in use to prevent moisture absorption and contamination.
