Description

Hexanedioic acid, polymer with 1,4-butanediol, 4,4'-diisocyanato-3,3'-dimethyl-1,1'-biphenyl, 1,3-diisocyanato-2-methylbenzene, 2,4-diisocyanato-1-methylbenzene and 1,2-ethanediol is a specialized polyurethane or polyurethane-urea copolymer, synthesized from a combination of adipic acid, butanediol, and aromatic diisocyanates. This engineered polymer is valued for its ability to impart a unique balance of mechanical strength, chemical resistance, and tailored flexibility to final formulations. It is primarily utilized by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries seeking high-performance polymeric materials.

Application

• High-Performance Coatings: Used as a resin component in industrial, automotive, and protective coatings requiring excellent durability, gloss, and chemical resistance.
• Specialty Adhesives & Sealants: Serves as a key polymer backbone in formulations demanding strong bonding, flexibility, and environmental stability.
• Engineering Elastomers: Employed in the production of castable or thermoplastic polyurethane elastomers for gaskets, rollers, and industrial parts.
• Textile & Leather Finishes: Acts as a binder or coating agent to provide water resistance, abrasion resistance, and a soft hand feel.
• Composite Materials: Utilized as a matrix resin or modifier in fiber-reinforced composites to enhance interfacial adhesion and toughness.
• Industrial Binders: Functions as a polymeric binder in non-woven fabrics, filters, and abrasive products.

Quality Control

Our production of this polyurethane copolymer adheres to strict quality management systems. Each batch is characterized for critical parameters including monomer content, molecular weight distribution, viscosity, and hydroxyl value to ensure batch-to-batch consistency for your formulations. A comprehensive Certificate of Analysis (COA) detailing these specifications is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); ensure containers are sealed immediately after use to prevent moisture absorption, which can affect product performance.
