Description

Hexanedioic Acid, Polymer With 2,2-Dimethyl-1,3-Propanediol And 2-Ethyl-2-(Hydroxymethyl)-1,3-Propanediol is a specialized polyester polyol, a key building block for high-performance polyurethane systems. This polymer offers a unique balance of properties derived from its neopentyl glycol and trimethylolpropane-based structure, providing excellent hydrolytic stability, chemical resistance, and controlled reactivity. It is essential for formulators in the coatings, adhesives, sealants, and elastomers (CASE) industries seeking to enhance product durability and performance under demanding conditions.

Application

• High-Performance Polyurethane Coatings: Used as a polyol component in two-component (2K) polyurethane coatings for industrial, automotive, and marine applications, offering excellent weatherability and chemical resistance.
• Elastomers and Sealants: Serves as a key raw material in the production of polyurethane elastomers and sealants that require superior mechanical properties and long-term durability.
• Adhesives and Binders: Formulated into specialty polyurethane adhesives for bonding plastics, metals, and composites, providing strong, flexible bonds.
• Resins for Composites: Utilized in the synthesis of polyester resins for fiber-reinforced plastics (FRP) and other composite materials.
• Flexible Foams: Can be incorporated into formulations for specialized flexible polyurethane foams requiring specific resilience and stability profiles.

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. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with each 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, well-ventilated area at room temperature (15-25°C/59-77°F). This product is hygroscopic (moisture-sensitive). Keep container tightly sealed when not in use to prevent moisture absorption, which can affect product performance.
