Description

Hexanedioic acid, polymer with 2,2-dimethyl-1,3-propanediol, 1,6-hexanediol, α-hydro-ω-hydroxypoly[ oxy(methyl-1,2-ethanediyl)], α-hydro-ω-hydroxypoly[ oxy(methyl-1,2-ethanediyl)] ether with 2-ethyl-2-(hydroxymethyl)-1,3-propanediol (3:1) and 1,1'-methyle is a specialized, high-performance polyester polyol copolymer designed for demanding industrial applications. This engineered polymer offers a unique balance of properties derived from its multi-component structure, including flexibility, hydrolytic stability, and controlled reactivity. It is a critical raw material for manufacturers seeking to produce high-quality polyurethane coatings, adhesives, sealants, and elastomers (CASE) with enhanced performance characteristics. Its consistent quality and reliable performance make it essential for formulators in the automotive, industrial maintenance, and specialty chemical sectors.

Application

This advanced polyester polyol is engineered for high-performance formulations where specific property profiles are required.

• High-Performance Polyurethane Coatings: Used as a key polyol component in two-component (2K) polyurethane coatings for automotive refinish, industrial maintenance, and plastic substrates, providing excellent flexibility, chemical resistance, and durability.
• Polyurethane Adhesives & Sealants: Serves as a base resin in formulating structural adhesives, flexible sealants, and potting compounds, contributing to strong adhesion and elastomeric properties.
• Polyurethane Elastomers: Employed in the production of cast, thermoplastic (TPU), and microcellular elastomers for applications requiring a combination of toughness, abrasion resistance, and low-temperature flexibility.
• Specialty Resins & Intermediates: Acts as a reactive intermediate for further chemical modification or as a component in hybrid polymer systems, such as polyester-polyurethane or polyester-acrylic blends.
• Industrial and Protective Coatings: Formulated into corrosion-resistant coatings for metal structures, pipelines, and marine environments, leveraging its stability and weatherability.

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, water content, and color are rigorously monitored using advanced analytical techniques including titration, gas chromatography (GC), and viscometry. A comprehensive Certificate of Analysis (COA) detailing all relevant specifications is provided with each shipment. Our quality system is designed to support formulations requiring compliance with various industrial and regulatory standards.

Storage

Preserve in a tightly closed container, protected from light. This product is hygroscopic (moisture-sensitive). Store in a cool, dry, and well-ventilated area at room temperature (typically 15-25°C/59-77°F). Keep the container tightly sealed when not in use to prevent moisture absorption, which can affect product performance. Store away from heat sources and incompatible materials such as strong acids, bases, and oxidizing agents.
