Description

Hexanedioic Acid, Polymer With 1,6-Diisocyanatohexane, 1,3-Diisocyanatomethylbenzene, 2,2-Dimethyl-1,3-Propanediol And 1,6-Hexanediol CAS NO 75915-56-9 is a high-performance, aliphatic-aromatic polyurethane prepolymer or resin. This specialized copolymer is engineered to deliver a unique balance of flexibility, chemical resistance, and durability for demanding industrial applications. It is essential for manufacturers seeking advanced material properties in coatings, adhesives, and elastomers.

Application

• High-Performance Coatings: Used as a key resin in industrial and protective coatings for metal, plastic, and concrete, offering excellent weatherability, abrasion resistance, and gloss retention.
• Advanced Adhesives & Sealants: Serves as a base polymer for formulating strong, flexible adhesives and sealants used in automotive assembly, construction, and composite bonding.
• Specialty Elastomers: A critical component in the production of cast, thermoplastic, or millable polyurethane elastomers for gaskets, rollers, and industrial parts requiring toughness.
• Textile & Leather Finishing: Employed in coatings for synthetic leather, waterproof textiles, and other fabric treatments to enhance durability and feel.
• Composite Materials: Acts as a matrix or binder in fiber-reinforced composites for automotive and aerospace components.
• Industrial Potting & Encapsulation: Used to protect sensitive electronic components from moisture, vibration, and environmental stress.

Quality Control

Our polyurethane polymer is manufactured under strict process controls to ensure batch-to-batch consistency. Quality is verified through a series of tests including viscosity, NCO/OH content, color, and solids determination. Certificates of Analysis (COA) detailing key specifications are available for every batch upon request, supporting 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 product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product performance.
