Description

Hexanedioic Acid, Polymer With 2,2-Dimethyl-1,3-Propanediol, 1,2-Ethanediol And 1,3-Isobenzofurandione is a specialized polyester resin, also known as a saturated polyester polyol, derived from adipic acid, neopentyl glycol, ethylene glycol, and phthalic anhydride. This engineered polymer is valued for its excellent chemical resistance, durability, and formulation flexibility, making it a critical component in high-performance coatings and adhesives. It is primarily sought by manufacturers in the industrial coatings, specialty plastics, and advanced adhesive sectors seeking to enhance product longevity and performance under demanding conditions.

Application

• High-Performance Industrial Coatings: Used as a key resin in formulations for coil coatings, automotive primers, and appliance finishes, providing excellent weatherability and chemical resistance.
• Polyurethane Systems: Serves as a polyester polyol component in the production of polyurethane adhesives, sealants, and elastomers.
• Powder Coatings: A vital raw material for thermosetting powder coatings, offering good flow and leveling properties for decorative and protective finishes on metal substrates.
• Specialty Inks and Overprint Varnishes: Imparts toughness, gloss, and adhesion in formulations for packaging and printing applications.
• Fiberglass Reinforced Plastics (FRP): Used in resin formulations for corrosion-resistant tanks, pipes, and structural components.
• Electrical Insulation: Employed in wire enamel and insulating varnishes due to its good dielectric properties and thermal stability.

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 against internal specifications. A comprehensive Certificate of Analysis (COA) detailing these results is provided with every 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); containers must be kept tightly sealed when not in use to prevent moisture absorption, which can affect product properties.
