Description

Hexanedioic Acid, Polymer With 2,2-Dimethyl-1,3-Propanediol, 2-Ethyl-2-(Hydroxymethyl)-1,3-Propanediol, Hexahydro-1,3-Isobeneofurandione And 1,3-Isobendofurandione is a high-performance, synthetic polyester polyol resin designed for demanding industrial applications. This specialized polymer offers a unique balance of properties derived from its multi-component structure, including rigidity, hydrolytic stability, and excellent reactivity. It is a critical raw material for formulators in the coatings, adhesives, sealants, and elastomers (CASE) industries seeking to enhance product durability and performance. Its consistent quality and reliable supply make it an essential component for advanced material development.

Application

• High-Performance Polyurethane Coatings: Serves as a key polyol component in two-component (2K) polyurethane systems for industrial, automotive, and protective coatings, providing excellent hardness, chemical resistance, and weatherability.
• Specialty Adhesives and Sealants: Used in formulating structural adhesives, potting compounds, and high-strength sealants where toughness, adhesion, and environmental resistance are paramount.
• Elastomers and Castable Urethanes: A vital ingredient for producing polyurethane elastomers with tailored properties such as abrasion resistance, flexibility, and load-bearing capacity for industrial parts and components.
• Powder Coatings: Functions as a reactive resin in carboxyl-functional polyester powders for hybrid or polyurethane-cured systems, contributing to flow, leveling, and final film properties.
• Composite Materials: Employed as a matrix resin or modifier in fiber-reinforced plastics (FRP) and other composite applications to improve interlaminar strength and thermal stability.
• Industrial and Maintenance Paints: Formulated into high-solids or solvent-borne coatings for machinery, pipelines, and structural steel, offering superior protection against corrosion and mechanical wear.

Quality Control

Our Hexanedioic Acid Polymer is manufactured under a stringent quality management system to ensure batch-to-batch consistency and performance reliability. Each production lot undergoes comprehensive analysis, including measurement of hydroxyl value, acid value, viscosity, and color. Certificates of Analysis (COA) detailing all relevant specifications are provided with every shipment. We are committed to meeting the quality standards required by the coatings and polymer industries.

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 / 59-77°F). 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 performance. Keep away from heat sources and open flame.
