Description

Hexanedioic acid, polymer with 1,3-diisocyanato-2-methylbenzene, 2,4-diisocyanato-1-methylbenzene, 2-ethyl-2-(hydroxymethyl)-1,3-propanediol and 2,2'-oxybis[ethanol] is a specialized polyurethane prepolymer or resin derived from adipic acid and a blend of toluene diisocyanate (TDI) isomers, modified with polyols. This engineered polymer is valued for its ability to impart durability, flexibility, and chemical resistance to final formulations. It is primarily utilized by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries seeking high-performance raw materials.

Application

• High-performance industrial and protective coatings for metal, concrete, and plastic substrates.
• Elastomeric sealants and adhesives requiring excellent weatherability and bond strength.
• Flexible and rigid polyurethane foams for insulation, automotive, and cushioning applications.
• Binder systems for composites and foundry sand.
• Potting and encapsulation compounds for electronic components.
• Specialty ink and overprint varnish formulations.

Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards and batch-to-batch consistency. Key parameters such as NCO content, viscosity, and acid value are strictly monitored. Certificates of Analysis (COA) are available upon request, and our quality management system supports compliance with relevant global regulatory frameworks.

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 after each use to prevent moisture absorption and premature reaction.
