Description

Hexanedioic Acid, Polymer With 1,4-Butanediol, 1,6-Diisocyanatohexane, 2,2-Dimethyl-1,3-Propanediol And 1,6-Hexanediol CAS NO 29891-05-2 is a specialized aliphatic polyester-polyurethane copolymer engineered for high-performance applications. This polymer offers a unique balance of flexibility, chemical resistance, and durability derived from its tailored monomer composition. It is primarily sought after by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as for advanced material synthesis requiring robust polymeric backbones.

Application

• High-Performance Coatings and Paints: Used as a resin binder in industrial, automotive, and marine coatings for excellent weatherability, gloss, and chemical resistance.
• Adhesives and Sealants: Serves as a key polyol component in polyurethane-based adhesives and sealants, providing strong bonding, flexibility, and moisture resistance.
• Elastomers and Thermoplastic Polyurethanes (TPU): A fundamental building block for manufacturing flexible, durable elastomers used in wheels, gaskets, hoses, and industrial belts.
• Composite Materials: Utilized in the production of fiber-reinforced plastics and composites for the aerospace and automotive sectors, enhancing impact resistance and structural integrity.
• Textile Finishing and Coatings: Applied to fabrics and non-wovens to impart water repellency, durability, and a soft hand feel.
• Specialty Resins for 3D Printing: Formulated into photopolymer resins for additive manufacturing, offering precise detail and mechanical strength in printed parts.

Quality Control

Our production of this aliphatic polyester-polyurethane polyol adheres to stringent quality management systems to ensure batch-to-batch consistency and performance reliability. Each lot is characterized for critical parameters including hydroxyl value, acid value, viscosity, and color. A comprehensive Certificate of Analysis (COA) detailing these specifications is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. This product is hygroscopic (moisture-sensitive). Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep the container tightly sealed when not in use to prevent moisture absorption, which can affect product performance.
