Description

Nonanedioic Acid, Polymer With 1,2-Ethanediol, 2-Ethyl-2-(Hydroxymethyl)-1,3-Propanediol And 1,3-Isobenzofurandione CAS NO 68797-54-6 is a specialized polyester polyol resin, synthesized from azelaic acid (nonanedioic acid), phthalic anhydride (1,3-isobenzofurandione), and a blend of diols and triols. This polymer is engineered to provide a unique balance of flexibility, chemical resistance, and reactivity, making it a versatile building block for high-performance coatings and adhesives. It is primarily utilized by formulators in the paints, coatings, and polymer industries seeking to enhance product durability and application properties.

Application

• High-Performance Industrial Coatings: As a key polyol component in two-component polyurethane (2K-PU) coatings for automotive, aerospace, and heavy-duty machinery, offering excellent weatherability and chemical resistance.
• Flexible Adhesives and Sealants: Used in the formulation of polyurethane-based adhesives and sealants that require good adhesion, flexibility, and hydrolytic stability.
• Synthetic Leather and Elastomers: Serves as a raw material in the production of polyurethane dispersions (PUDs) for synthetic leather, artificial leather (PU leather), and flexible elastomers.
• Corrosion-Resistant Primers: Incorporated into primer formulations for metal substrates, providing enhanced corrosion protection and substrate adhesion.
• Plasticizers and Modifiers: Acts as a polymeric plasticizer or modifier for other resin systems to improve flexibility and low-temperature performance.
• UV-Curable Resin Systems: Can be functionalized for use in ultraviolet (UV) light-curable coating and ink formulations, contributing to rapid cure and film properties.

Quality Control

Our production of this specialty polyester polyol adheres to strict quality management protocols to ensure batch-to-batch consistency and performance reliability. Key parameters such as hydroxyl value (OHV), acid value, viscosity, and color are rigorously monitored. A comprehensive Certificate of Analysis (COA) detailing these 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). Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect product properties.
