Description

Hexanedioic Acid, Polymer With 2,2-Dimethyl-1,3-Propanediol, 1,2-Ethanediol And 1,6-Hexanediol is a high-performance, hydroxyl-functional polyester polyol. This specialized polymer is engineered to deliver exceptional consistency and reactivity, making it a critical raw material for formulating advanced polyurethane systems. It is essential for manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries seeking to enhance product durability, flexibility, and chemical resistance.

Application

This versatile polyester polyol serves as a foundational component in numerous high-performance applications:

• High-Performance Polyurethane Coatings: Used in automotive clear coats, industrial maintenance paints, and protective marine coatings for superior gloss retention and weatherability.
• Elastomers and Castables: Formulates durable rollers, wheels, gaskets, and industrial parts requiring excellent tensile strength and abrasion resistance.
• Adhesives and Sealants: Provides strong bonding properties and flexibility in construction, automotive assembly, and aerospace sealants.
• Thermoplastic Polyurethanes (TPU): A key ingredient for producing flexible films, cables, hoses, and breathable textiles.
• Rigid and Flexible Foams: Imparts structural integrity and resilience in insulation panels, packaging materials, and cushioning applications.
• UV-Curable Systems: Enables fast-curing, low-VOC formulations for wood, plastic, and metal finishes.

Quality Control

Our production of this polyester polyol adheres to strict quality management protocols to ensure batch-to-batch consistency and performance reliability. Key parameters including hydroxyl value, acid value, viscosity, and color are rigorously tested. Certificates of Analysis (COA) documenting full specifications are provided with every shipment. Our quality system is designed to support formulations requiring compliance with various industry standards.

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). This product is hygroscopic (moisture-sensitive). Keep container tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect product performance. Keep away from heat sources and incompatible materials such as strong acids, bases, and oxidizing agents.
