Description

Hexanedioic Acid, Polymer With 2,2-Dimethyl-1,3-Propanediol And 3-Hydroxy-2-(Hydroxymethyl)-2-Methylpropanoic Acid is a specialized, high-performance polyester polyol designed for demanding industrial applications. This polymer is valued for its excellent hydrolytic stability, low viscosity, and ability to impart flexibility and durability to final products. It is a critical raw material for manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as for advanced polyurethane systems. Its consistent quality and reliable performance make it an essential component for formulators seeking to enhance product properties.

Application

• High-Performance Polyurethane Coatings: Used as a key polyol component in two-component (2K) polyurethane coatings for automotive, industrial, and protective applications, providing excellent weatherability, chemical resistance, and flexibility.
• Adhesives and Sealants: Serves as a building block in the formulation of flexible and durable polyurethane adhesives and sealants for construction, automotive assembly, and packaging.
• Elastomers and Castable Urethanes: A fundamental ingredient for producing polyurethane elastomers with a balanced profile of toughness, abrasion resistance, and low-temperature flexibility.
• Resins for Composite Materials: Utilized in the synthesis of unsaturated polyester resins or as a modifier to improve the impact resistance and processing characteristics of composite materials.
• Specialty Plasticizers and Additives: Can be employed in the creation of polymeric plasticizers or as a reactive intermediate for specialty additives that enhance material performance.

Quality Control

Our production of this advanced 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, and color are rigorously tested against internal specifications. A comprehensive Certificate of Analysis (COA) detailing these results is provided with each shipment. We support our global clients by ensuring our materials and processes align with relevant industry and regulatory expectations.

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). Containers must be kept tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect product quality and performance in downstream reactions.
