Description

Hexanedioic Acid, Polymer With 2,2-Dimethyl-1,3-Propane-Diol, 1,2-Ethanediol, 1,3-Isobenzofurandione And 1,2-Propanediol is a specialized polyester polyol copolymer designed for high-performance applications. This engineered polymer offers a unique balance of properties derived from its multi-component structure, including flexibility, chemical resistance, and controlled reactivity. It is primarily utilized by formulators in the coatings, adhesives, sealants, and elastomers (CASE) industries seeking to enhance product durability and performance.

Application

• High-Performance Polyurethane Coatings: Serves as a key polyol component in the formulation of durable, weather-resistant, and chemical-resistant coatings for automotive, industrial, and architectural applications.
• Adhesives and Sealants: Used to develop flexible yet strong polyurethane-based adhesives and sealants with excellent adhesion to various substrates.
• Elastomers: A critical raw material for producing cast, thermoplastic, or millable polyurethane elastomers requiring a specific balance of hardness, tensile strength, and elongation.
• Resin Modifier: Acts as a reactive modifier in other polymer systems (e.g., unsaturated polyesters, alkyds) to impart flexibility, impact resistance, or improved weatherability.
• Composite Materials: Employed in the production of fiber-reinforced composites and gel coats, contributing to matrix toughness and interfacial bonding.

Quality Control

Our production of this specialty polyester polyol adheres to strict quality management systems. Each batch is characterized by key parameters including hydroxyl value, acid value, viscosity, and color to ensure consistent performance and batch-to-batch reproducibility. Certificates of Analysis (COA) detailing these specifications are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (typically 15-25°C). This product is hygroscopic (moisture-sensitive); ensure containers are sealed after use to prevent moisture absorption, which can affect reactivity. Keep away from strong oxidizing agents and excessive heat sources.
