Description

1,3-Benzenedicarboxylic Acid, Polymer With 2,2-Dimethyl-1,3-Propanediol, 2-Ethyl-2-(Hydroxymethyl)-1,3-Propanediol, Hexanedioic Acid And 1,6-Hexanediol is a high-performance, branched polyester polyol designed for demanding industrial applications. This specialized polymer offers a unique balance of properties, including excellent chemical resistance, mechanical strength, and formulation versatility, making it a critical component for advanced material synthesis. It is primarily utilized by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as in polyurethane foam production, where its specific structure imparts enhanced performance characteristics to the final product.

Application

• High-Performance Polyurethane Coatings: Serves as a key polyol component in two-component (2K) polyurethane coatings for industrial, automotive, and protective applications, providing excellent durability, gloss, and chemical resistance.
• Adhesives and Sealants: Used in formulating polyurethane-based adhesives and sealants, contributing to strong bonding strength, flexibility, and environmental stability.
• Elastomers: A vital raw material for casting, thermoplastic, and millable polyurethane elastomers used in wheels, rollers, gaskets, and other impact-resistant parts.
• Rigid and Flexible Foams: Imparts specific structural and physical properties when used as a polyol in the production of rigid insulation foams and specialized flexible foams.
• Resin Modifiers: Acts as a modifier for other polymer resins (e.g., alkyds, polyesters) to enhance flexibility, adhesion, and weatherability.
• Industrial and Composite Materials: Employed in the synthesis of composite materials, binders, and encapsulants for electrical and construction applications.

Quality Control

Our production of this branched polyester polyol adheres to stringent quality management protocols to ensure batch-to-batch consistency and performance reliability. Each lot undergoes comprehensive analysis, including measurement of hydroxyl value, acid value, viscosity, color, and moisture content. Certificates of Analysis (COA) detailing these specifications are provided and available upon request, supporting 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 (typically 15-25°C). Keep away from heat sources and open flame. As this material may be hygroscopic, containers should be kept tightly sealed when not in use to prevent moisture absorption.
