Description

Hexanedioic Acid, Polymer With 1,2-Ethanediol, 1,1-Methylenebis4-Isocyanatobenzene And 1,2-Propanediol is a specialized polyurethane prepolymer or resin derived from adipic acid, ethylene glycol, propylene glycol, and MDI. This engineered polymer is valued for its ability to impart enhanced flexibility, toughness, and chemical resistance to final formulations. It is primarily utilized by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries seeking to develop high-performance, durable products.

Application

• High-Performance Coatings & Paints: Used as a key resin component to improve flexibility, adhesion, and chemical/abrasion resistance in industrial, automotive, and protective coatings.
• Adhesives & Sealants: Serves as a base polymer for formulating structural and elastic adhesives with strong bonding properties and durability under stress.
• Elastomers & Castable Urethanes: Employed in the production of flexible polyurethane parts, gaskets, rollers, and wheels requiring a balance of toughness and elasticity.
• Composite Materials: Acts as a matrix resin or modifier in fiber-reinforced composites to enhance impact resistance and interfacial bonding.
• Textile & Leather Finishing: Utilized in coatings and binders to provide durable, flexible finishes with improved water resistance and feel.
• Specialty Binders: Incorporated into formulations for non-woven fabrics, filters, and other materials where flexible yet strong binding is required.

Quality Control

Our production of this polyurethane polymer adheres to strict quality management protocols to ensure batch-to-batch consistency and performance reliability. Key parameters such as NCO content, hydroxyl value, viscosity, and acid number 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 container, protected from light. This material is hygroscopic (moisture-sensitive). Store in a cool, dry, and well-ventilated area at room temperature (typically 15-25°C). Keep containers tightly sealed when not in use to prevent moisture absorption and contamination, which can affect reactivity and properties.
