Description

1,3-Benzenedicarboxylic Acid, Polymer With 2-Ethyl-2-(Hydroxymethyl)-1,3-Propanediol, Hexanedioic Acid And 1,2-Propanediol CAS NO 26282-28-0 is a high-performance, branched polyester polyol resin. This specialized polymer is engineered to deliver a unique balance of flexibility, chemical resistance, and durability in demanding industrial applications. It is a critical raw material for manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries seeking to enhance product performance.

Application

• High-Performance Polyurethane Coatings: Serves as a key polyol component in two-component (2K) polyurethane systems for industrial, automotive, and protective coatings, providing excellent weatherability and mechanical properties.
• Elastomers and Sealants: Used in the formulation of flexible polyurethane elastomers, gaskets, and construction sealants where resilience and adhesion are paramount.
• Adhesives and Binders: Imparts strong bonding characteristics and toughness in structural and laminating adhesives.
• Composite Materials: Acts as a matrix resin or modifier in fiber-reinforced plastics (FRP) and other composite systems.
• Specialty Resins for 3D Printing: Utilized in vat photopolymerization (e.g., SLA/DLP) to create durable, functional prototypes and end-use parts.

Quality Control

Every batch of our polyester polyol is produced under strict quality management systems and undergoes comprehensive analytical testing to ensure consistent performance. Key parameters such as hydroxyl value, acid value, viscosity, and color are rigorously controlled. A Certificate of Analysis (COA) detailing all test results is provided with each shipment to guarantee specification compliance.

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). Keep away from heat sources and open flame. This product is hygroscopic (moisture-sensitive); ensure containers are sealed after use to prevent absorption of atmospheric moisture, which can affect product performance.
