Description

Hexanedioic acid, polymer with 1,6-diisocyanato-2,2,4-trimethylhexane, oxybis[propanol] and α,α',α''- 1,2,3-propanetriyltris[ω-hydroxypoly[oxy(methyl -1,2-ethanediyl)]] CAS NO 68958-73-6 is a specialized polyurethane prepolymer or resin derived from adipic acid, a trimethyl-substituted hexane diisocyanate, and a blend of polyether polyols. This complex polymer is engineered to deliver exceptional flexibility, toughness, and adhesion in demanding coating and adhesive formulations. It is a critical raw material for manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries who require high-performance, tailored polymer properties.

Application

• High-Performance Coatings: Used as a key binder in industrial, automotive, and protective coatings requiring excellent chemical resistance, durability, and weatherability.
• Specialty Adhesives & Sealants: Serves as a base polymer for formulating flexible, high-strength adhesives and sealants with strong substrate adhesion.
• Elastomer Production: Acts as a prepolymer for manufacturing castable polyurethane elastomers used in rollers, wheels, and industrial parts.
• Composite Materials: Employed as a matrix resin or modifier in composite systems to enhance impact resistance and interfacial bonding.
• Textile & Leather Finishing: Utilized in coatings and finishes to provide durable, flexible, and water-resistant surfaces.
• Flexible Packaging Inks & Overprint Varnishes: Imparts flexibility and adhesion in ink and varnish formulations for films and foils.

Quality Control

Our production of this polyurethane polymer adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as NCO content, viscosity, solids content, and color are rigorously monitored. A comprehensive Certificate of Analysis (COA) detailing all relevant specifications is provided with each shipment to support your quality assurance protocols.

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 moisture-sensitive (hygroscopic). Keep container tightly sealed when not in use to prevent moisture absorption and contamination. Keep away from heat and incompatible materials such as strong acids, bases, and oxidizing agents.
