Description

Hexanedioic acid, polymer with 1,4-butanediol, 2-ethyl-2-(hydroxymethyl)-1,3-propanediol, 1,6-hexanediol, 3-hydroxy-2-(hydroxymethyl)-2-methylpropanoic acid and 5-isocyanato-1-(isocyanatomethyl)-1,3,3-trimethylcyclohexane, compd. with N,N-diethylethanamine is a specialized, high-performance polyurethane prepolymer or resin intermediate. This compound is engineered to deliver exceptional mechanical properties, chemical resistance, and formulation versatility for demanding industrial applications. It is primarily sought by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as for advanced composite materials.

Application

• High-Performance Coatings: Used as a key resin component in durable industrial, automotive, and protective coatings requiring excellent gloss retention, abrasion resistance, and weatherability.
• Advanced Adhesives & Sealants: Serves as a backbone polymer for formulating structural adhesives, potting compounds, and high-strength sealants with strong bonding and flexibility.
• Elastomer Production: Acts as a prepolymer for manufacturing castable polyurethane elastomers used in rollers, wheels, gaskets, and impact-absorbing components.
• Composite Materials: Utilized in the production of fiber-reinforced plastics (FRP) and other composites, enhancing matrix toughness and interfacial adhesion.
• Specialty Inks & Overprint Varnishes: Imparts durability, chemical resistance, and a high-quality finish in packaging and printing applications.
• Industrial Fabric Coatings: Applied to textiles and nonwovens to create waterproof, breathable, and mechanically robust fabrics for technical uses.

Quality Control

Our production of this polyurethane intermediate adheres to strict quality management systems, ensuring batch-to-batch consistency for your formulations. Key parameters such as NCO content, viscosity, acid value, and solids content are rigorously monitored. A comprehensive Certificate of Analysis (COA) detailing assay, identity, and impurity profiles is provided with every 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 (15-25°C). This material is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product performance. Keep away from heat, sparks, and open flame.
