Description

Hexanedioic Acid, Polymer With 2,2-Dimethyl-1,3-Propanediol, 2-Ethyl-2-(Hydroxymethyl)-1,3-Propanediol And Hexahydro-1,3-Isobenzofurandione CAS NO 69153-52-2 is a specialized, high-performance polyester polyol resin. This engineered polymer is valued for its excellent mechanical properties, chemical resistance, and versatility in formulating durable coatings and adhesives. It is primarily sought by manufacturers in the coatings, elastomers, and specialty plastics industries seeking to enhance product performance and durability.

Application

• High-Performance Coatings: Used as a key resin in industrial, automotive, and marine coatings for superior weatherability, gloss, and chemical resistance.
• Polyurethane Elastomers: Serves as a polyol component in the production of flexible and rigid polyurethane foams, cast elastomers, and sealants.
• Adhesives and Sealants: Formulated into structural and specialty adhesives requiring strong bonding, flexibility, and environmental stability.
• Composite Materials: Acts as a matrix resin or modifier in fiber-reinforced plastics (FRP) and other composite systems.
• Electrical Encapsulation: Employed in potting and encapsulation compounds for electronic components due to its insulating properties.
• Industrial Finishes: A critical component in powder coatings and coil coatings that demand excellent flow and finish.

Quality Control

Our production of this polyester polyol 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. Certificates of Analysis (COA) documenting full specifications are 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). This product is hygroscopic (moisture-sensitive); ensure containers are sealed immediately after use to prevent moisture absorption, which can affect product performance.
