Description

Hexanedioic Acid, Polymer With 1,2-Ethanediol, 2-Ethyl-2-(Hydroxymethyl)-1,3-Propanediol And Oxybispropanol CAS NO 80121-87-5 is a specialized, high-performance polyester polyol designed for demanding industrial applications. This polymer is valued for its ability to impart specific mechanical properties, chemical resistance, and formulation flexibility to final products. It is primarily utilized by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as in polyurethane foam production.

Application

• High-Performance Polyurethane Coatings: Used as a key polyol component in two-component (2K) polyurethane coatings for industrial, automotive, and protective applications, offering excellent durability and chemical resistance.
• Adhesives and Sealants: Serves as a building block in formulating polyurethane-based adhesives and sealants, providing strong bonding, flexibility, and adhesion to diverse substrates.
• Elastomers: A critical raw material for manufacturing cast, thermoplastic, or millable polyurethane elastomers used in wheels, rollers, gaskets, and industrial parts.
• Flexible and Rigid Foams: Can be formulated into specialized polyurethane foams for applications requiring a balance of comfort, support, or insulation properties.
• Resins for Composites: Employed in the synthesis of unsaturated polyester resins or as a modifier to enhance the toughness and performance of composite materials.
• Industrial and Maintenance Paints: Contributes to the formulation of high-solids, solvent-borne, or water-borne coatings that require robust weatherability and mechanical strength.

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 such as hydroxyl value, acid value, viscosity, and color are rigorously tested. A comprehensive Certificate of Analysis (COA) detailing all specification 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 (typically 15-25°C). This product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect product performance.
