Description

Hexanedioic Acid, Polymer With 2-Ethyl-2-(Hydroxymethyl)-1,3-Propanediol, 1,3-Isobenzofurandione And 2,2-Oxybisethanol CAS NO 55680-35-8 is a specialized polyester polyol resin designed for high-performance applications. This polymer is valued for its ability to impart excellent mechanical properties, chemical resistance, and durability to final products. It is primarily sought by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as for advanced composite materials.

Application

• High-Performance Industrial Coatings: Used as a key polyol component in polyurethane coatings for metal, plastic, and concrete, providing superior hardness, flexibility, and corrosion resistance.
• Adhesives and Sealants: Serves as a building block in polyurethane-based adhesives and sealants, enhancing bond strength, elasticity, and environmental stability.
• Elastomers and Castable Urethanes: Formulated into durable elastomers for industrial rollers, wheels, gaskets, and impact-absorbing components.
• Composite Materials: Acts as a resin matrix or modifier in fiber-reinforced plastics (FRP) and other composites, improving interlaminar adhesion and toughness.
• Electrical Potting and Encapsulation: Utilized in systems that protect sensitive electronic components from moisture, vibration, and thermal stress.
• Specialty Inks and Overprint Varnishes: Incorporated into formulations requiring excellent substrate adhesion, abrasion resistance, and gloss.

Quality Control

Our polyester polyol resin is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent performance characteristics such as hydroxyl value, acid value, viscosity, and color. Certificates of Analysis (COA) detailing these specifications are available upon request 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); containers must be kept sealed to prevent absorption of atmospheric moisture, which can affect product performance.
