Description

1,3-Benzenedicarboxylic Acid, Polymer With Hexanedioic Acid And 2,2-Oxybisethanol, Reaction Products With 1,1-Methylenebis4-Isocyanatobenzene is a high-performance polyurethane prepolymer or resin intermediate. This specialized chemical is engineered to deliver enhanced durability, flexibility, and adhesion in demanding industrial formulations. It is primarily utilized by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries seeking to improve the mechanical and chemical resistance properties of their final products.

Application

• High-Performance Coatings: Used as a key binder in industrial and protective coatings for metal, concrete, and plastic substrates, offering excellent weatherability and chemical resistance.
• Adhesives & Sealants: Serves as a critical component in formulating structural adhesives, laminating adhesives, and high-strength sealants with superior bonding strength and flexibility.
• Elastomers and Castables: Employed in the production of polyurethane elastomers, gaskets, and molded parts that require a balance of toughness and elasticity.
• Composite Materials: Functions as a matrix resin or compatibilizer in fiber-reinforced composites for automotive and aerospace applications.
• Industrial Fabric Coatings: Used to coat technical textiles, conveyor belts, and tarpaulins to impart abrasion resistance, waterproofing, and durability.
• Specialty Inks: Incorporated into formulations for flexible packaging inks and overprint varnishes to enhance adhesion and scuff resistance.

Quality Control

Our production of this polyurethane intermediate adheres to strict quality management protocols to ensure batch-to-batch consistency and performance reliability. Key parameters such as isocyanate (NCO) content, viscosity, and acid value are rigorously monitored. A comprehensive Certificate of Analysis (COA) detailing all relevant specifications is provided with each shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed, moisture-proof container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures recommended for polyurethane prepolymers (typically 15-25°C). Keep away from heat, open flames, and sources of moisture. Under these conditions, the product maintains optimal stability.
