Description

Hexanedioic acid, polymer with 1,3-diisocyanato-2-methylbenzene, 2,4-diisocyanato-1-methylbenzene and 1,6-hexanediol Adipic acid, 1,6-hexanediol, toluene-2,4-diisocyanate, toluene-2,6-diisocyanate polymer is a specialized polyurethane prepolymer or resin derived from adipic acid, hexanediol, and a mixture of toluene diisocyanate (TDI) isomers. This polymer is engineered to deliver exceptional durability, chemical resistance, and versatile processing characteristics, making it a critical raw material for high-performance coatings and elastomers. It is primarily needed by formulators and manufacturers in the protective coatings, adhesives, sealants, and specialty elastomer industries seeking to enhance product longevity and performance under demanding conditions.

Application

• High-performance polyurethane coatings for industrial maintenance, marine, and automotive applications.
• Elastomeric binders and sealants requiring excellent flexibility and adhesion.
• Adhesive formulations for bonding plastics, metals, and composites.
• Fabric coatings and textile finishes to impart water resistance and durability.
• Wire and cable insulation compounds.
• Gaskets, rollers, and industrial molded parts with good mechanical properties.
• Base component for further chemical modification in specialty polymer synthesis.

Quality Control

Our production of this polyurethane polymer adheres to strict batch-to-batch consistency protocols. Quality is monitored through key parameters including NCO content, viscosity, acid value, and hydroxyl number. A comprehensive Certificate of Analysis (COA) is provided with each shipment, detailing specifications and test results. Our quality management system is designed to support formulations requiring reliable performance and compliance with industry standards.

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 / 59-77°F). This product is hygroscopic (moisture-sensitive) and must be protected from atmospheric moisture to prevent premature reaction and viscosity increase. Keep away from heat, sparks, and open flame.
