Description

Hexanedioic acid, polymer with 1,6-diisocyanatohexane, 1,3-diisocyanatomethylbenzene, 2,2-dimethyl-1,3-propanediol, 1,6-hexanediol and 5-isocyanato-1-(isocyanatomethyl)-1,3,3-trimethylcyclohexane is a high-performance, aliphatic-aromatic polyurethane prepolymer or resin. This specialized polymer is engineered to deliver an exceptional balance of durability, chemical resistance, and weatherability for demanding industrial applications. It is a critical raw material for formulators and manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries seeking to enhance product performance.

Application

• High-Performance Coatings: Formulation of premium two-component (2K) polyurethane coatings for automotive, aerospace, industrial maintenance, and marine applications requiring excellent gloss retention and UV resistance.
• Advanced Adhesives & Sealants: Used as a base resin for structural adhesives, flexible sealants, and potting compounds where strong bonding and environmental durability are paramount.
• Elastomer Production: Serves as a key component in the manufacture of cast, thermoplastic, or millable polyurethane elastomers for rollers, wheels, gaskets, and impact-absorbing parts.
• Composite Materials: Acts as a matrix resin or binder in fiber-reinforced composites, providing toughness and resistance to moisture and chemicals.
• Industrial Finishes: Base for protective finishes on flooring, concrete, pipelines, and other infrastructure exposed to harsh conditions.
• Specialty Inks and Overprint Varnishes: Provides scratch resistance and flexibility in high-end printing applications for packaging and labels.

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 every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed, moisture-proof container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures recommended for polyurethane prepolymers (typically 15-25°C). Keep away from heat, sparks, and open flame. Due to the reactive isocyanate groups, moisture must be strictly excluded to prevent polymerization and gelation. Shelf life is typically 6-12 months under these conditions.
