Description

1,3-Benzenedicarboxylic Acid, Polymer With (E)-2-Butenedioic Acid, 2,2'-Oxybis[Ethanol] And 1,2-Propanediol is a specialized polyester polyol copolymer. This engineered polymer is valued for its ability to impart specific performance characteristics, such as enhanced flexibility, adhesion, and chemical resistance, to final formulations. It is a critical raw material for manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries seeking to develop high-performance polyurethane products.

Application

• Polyurethane Coatings Binder: Serves as a key polyol component in the formulation of high-performance, two-component polyurethane coatings for industrial, automotive, and marine applications, providing excellent durability and chemical resistance.
• Adhesive & Sealant Formulations: Used in the synthesis of polyurethane adhesives and sealants, contributing to strong substrate adhesion, flexibility, and long-term performance in construction and assembly.
• Elastomer Production: Acts as a building block for castable or thermoplastic polyurethane elastomers used in gaskets, wheels, and industrial parts requiring a balance of toughness and elasticity.
• Resin Modification: Employed to modify the properties of other polymer resins, enhancing characteristics like impact resistance, weatherability, and compatibility with various substrates.
• Specialty Ink Vehicles: Utilized in the development of specialty inks and overprint varnishes that demand specific film properties and adhesion to challenging surfaces.

Quality Control

Our production of this specialty polyester polyol adheres to strict quality management protocols. Each batch undergoes rigorous analytical testing to ensure consistent hydroxyl value, acid value, viscosity, and molecular weight distribution. Certificates of Analysis (COA) detailing these specifications are provided with every shipment to guarantee traceability and compliance with your formulation requirements.

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 a moisture-sensitive material, the container must be kept tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect product performance.
