Description

Hexanedioic acid, polymer with 2,2-dimethyl-1,3-propanediol, 1,6-hexanediol, 3-hydroxy-2-(hydroxymethyl)-2-methylpropanoic acid and 5-isocyanato-1-(isocyanatomethyl)-1,3,3-trimethylcyclohexane CAS NO 125826-45-1 is a high-performance, aliphatic polyester-polyurethane copolymer designed for demanding industrial applications. This specialized polymer offers an exceptional balance of durability, chemical resistance, and processing versatility, making it a critical raw material for advanced material formulations. It is primarily utilized by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as in specialty plastics and composite materials.

Application

• High-Performance Coatings: Used as a resin component in automotive, industrial, and protective coatings for enhanced weatherability, flexibility, and chemical resistance.
• Advanced Adhesives & Sealants: Serves as a key polymer backbone in structural adhesives, laminating agents, and flexible sealants requiring strong bonding and durability.
• Specialty Elastomers: Formulated into castable or thermoplastic polyurethane (TPU) elastomers for gaskets, rollers, and impact-resistant components.
• Composite Materials: Acts as a matrix resin or modifier in fiber-reinforced plastics (FRP) and other composite systems to improve toughness and interlayer adhesion.
• Industrial and Maintenance Paints: Provides a robust film-forming base for heavy-duty maintenance paints and corrosion-resistant primers.
• Flexible Packaging Inks and Overprint Varnishes: Imparts excellent adhesion and low-temperature flexibility in printing applications for films and foils.

Quality Control

Our production of this polymer adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as hydroxyl value, acid value, viscosity, and color are rigorously tested against internal specifications. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with each shipment to support your quality assurance and regulatory compliance needs.

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 / 59-77°F). Due to its hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed when not in use to prevent moisture absorption, which can affect product performance. Keep away from heat sources and incompatible materials.
