Description

1,3-Benzenedicarboxylic acid, polymer with hexanedioic acid, .alpha.-hydro-.omega.-hydroxypolyoxy(methyl-1,2-ethanediyl), 1,1-methylenebis4-isocyanatobenzene, 2,2-oxybisethanol, 1,2-propanediol and .alpha.,.alpha.,.alpha.-1,2,3-propanetriyltris.omega.-hyd is a high-performance, multi-component polymeric material engineered for demanding industrial applications. This specialized polymer offers a unique balance of properties derived from its complex co-polymeric structure, making it a critical raw material for advanced material formulations. It is essential for manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries seeking to enhance product durability and performance.

Application

• High-Performance Coatings and Paints: Used as a key resin or binder component in industrial, automotive, and protective coatings to improve chemical resistance, adhesion, and weatherability.
• Advanced Adhesives and Sealants: Serves as a base polymer for formulating structural adhesives, potting compounds, and elastic sealants with excellent bonding strength and flexibility.
• Specialty Elastomers and Urethane Systems: A crucial intermediate or prepolymer in the production of polyurethane elastomers, foams, and castable rubber products.
• Composite Materials: Employed as a matrix resin or toughening agent in fiber-reinforced plastics (FRP) and other composite systems to enhance mechanical properties.
• Industrial Fabric Coatings and Textile Finishes: Used to create durable, water-resistant, and flexible coatings for technical textiles, tarpaulins, and conveyor belts.
• Encapsulation and Potting Compounds: Ideal for electronic and electrical applications where protection from moisture, vibration, and environmental stress is required.

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 hydroxyl value (OHV), isocyanate content (NCO%), viscosity, and color are rigorously monitored. A comprehensive Certificate of Analysis (COA) detailing all relevant specifications is provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures recommended for polyurethane precursors, typically between 15°C and 25°C (59°F and 77°F). Keep away from heat, sparks, and open flame. Containers must be kept tightly sealed to prevent moisture absorption, which can affect product performance.
