Description

Hexanedioic Acid, Polymer With 1,4-Butanediol, 2-Ethyl-2-(Hydroxymethyl)-1,3-Propanediol And 4-Hydroxy-γ-(4-Hydroxyphenyl) -γ-Methylbenzenebutanoic Acid is a specialized, high-performance polyester polyol designed for demanding industrial applications. This polymer is engineered to deliver exceptional consistency and reactivity, making it a critical raw material for advanced material synthesis. It is primarily sought after by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as for producing high-grade polyurethane foams and resins.

Application

• High-Performance Polyurethane Coatings: Used as a key polyol component in two-component (2K) polyurethane coatings for automotive, industrial, and protective finishes, offering excellent durability, chemical resistance, and gloss.
• Elastomers and Sealants: Serves as a building block for polyurethane elastomers and sealants that require a balance of flexibility, tensile strength, and weatherability.
• Adhesives Formulation: Imparts strong adhesion and cohesion properties in structural and laminating adhesives for composites, plastics, and metals.
• Rigid and Flexible Foams: Can be formulated into specialized polyurethane foams for insulation, cushioning, and composite core applications.
• Resin Modifier: Acts as a reactive modifier in polyester and alkyd resins to enhance properties like flexibility, adhesion, and hydrolytic stability.
• Industrial and Composite Binders: Utilized in binder systems for foundry sands, abrasives, and non-woven materials due to its robust polymer structure.

Quality Control

Our Hexanedioic Acid Polymer is produced under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure consistent hydroxyl value, acid value, viscosity, and moisture content, meeting precise specifications for polyurethane formulation. Certificates of Analysis (COA) detailing all critical parameters 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). Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect product performance.
