Description

Hexanedioic Acid, Polymer With 2,2-Dimethyl-1,3-Propanediol, 2-Ethyl-2-(Hydroxymethyl)-1,3-Propanediol, Hexahydro-1,3-Isobenzofurandione And 2,2-Iminobisethanol CAS NO 65970-50-5 is a specialized, high-performance polyester polyol resin designed for demanding industrial applications. This polymer is valued for its ability to impart excellent mechanical properties, chemical resistance, and durability to final products. It is primarily sought after by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as for advanced polyurethane systems.

Application

• High-Performance Polyurethane Coatings: Used as a key polyol component in formulations for industrial, automotive, and protective coatings requiring superior weatherability, gloss, and hardness.
• Elastomers and Sealants: Serves as a building block for polyurethane elastomers and sealants that demand excellent tensile strength, flexibility, and resistance to oils and chemicals.
• Adhesives: Incorporated into structural and laminating adhesive formulations to enhance bond strength, thermal stability, and durability.
• Resin Modifier: Acts as a modifier for other polymer systems to improve toughness, adhesion, and overall performance characteristics.
• Industrial and Composite Materials: Utilized in the production of composite materials, castings, and other engineered plastic components.

Quality Control

Our production of this specialty polyester polyol adheres to strict quality management protocols to ensure batch-to-batch consistency and performance. Key parameters such as hydroxyl value, acid value, viscosity, and color are rigorously tested. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with each shipment to support your quality assurance and formulation processes.

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 when not in use to prevent absorption of atmospheric moisture, which can affect product performance.
