Description

1,4-Benzenedicarboxylic Acid, Polymer With 1,2-Ethanediol And 2,2'-Oxybis[Ethanol] CAS NO 25052-77-1 is a high-performance, water-soluble polyester polymer derived from terephthalic acid and glycols. This versatile polymer is engineered to deliver excellent film-forming, binding, and dispersing properties, making it a critical additive in numerous industrial formulations. It is primarily sought by manufacturers in the coatings, adhesives, textile, and personal care industries for its ability to modify rheology and enhance product performance.

Application

• Coatings & Inks: Acts as a rheology modifier and dispersing agent in water-based paints, lacquers, and printing inks to improve flow and stability.
• Adhesives & Sealants: Used as a film-forming agent and tackifier in aqueous adhesive systems, providing strong binding power.
• Textile Processing: Serves as a sizing agent, lubricant, or finishing agent to improve fiber handling and fabric quality.
• Personal Care & Cosmetics: Functions as a film former and viscosity controller in hair sprays, styling gels, and skin care products.
• Industrial Cleaners: Employed as a builder and anti-redeposition agent in detergent formulations for enhanced cleaning efficacy.
• Paper & Packaging: Utilized as a coating additive to improve gloss, printability, and barrier properties of paper products.

Quality Control

Our production of this polymer adheres to strict quality management systems. Every batch is tested against key parameters including viscosity, acid value, solid content, and color to ensure batch-to-batch consistency and performance reliability. Certificates of Analysis (COA) documenting these results are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); ensure containers are sealed immediately after use to prevent moisture absorption, which can affect product properties.
