Description

Poly(Oxy-1,2-Ethanediyl), .Alpha.-Methyl-.Omega.-Hydroxy-, 2-Hydroxy-3-(.Gamma.-.Omega.-Perfluoro-C6-20-Alkyl)Thiopropyl Ethers is a specialized fluorinated polyether surfactant that combines the surface-modifying power of perfluoroalkyl groups with the solubility and processability of a polyether backbone. This unique structure provides exceptional surface tension reduction, oil and water repellency, and chemical stability, making it a critical performance additive. It is primarily needed by formulators in the coatings, fire-fighting foam, and specialty polymer industries seeking to impart durable hydrophobic and oleophobic properties to their products.

Application

• As a key surfactant and leveling agent in high-performance fluoropolymer coatings and paints to improve wetting and reduce surface defects.
• As a critical foam stabilizer and film-forming component in aqueous film-forming foams (AFFF) and other fire-fighting formulations.
• As an additive in textile and leather treatments to provide durable water and oil repellency (DWR/DOR).
• As a surface modifier and compatibilizer in the production of specialty plastics and elastomers to enhance surface properties.
• As an emulsifier and stabilizer in the formulation of fluorinated specialty chemicals and industrial fluids.
• In the manufacture of anti-fogging and anti-graffiti coatings for optical and architectural applications.

Quality Control

Our production of this fluorinated polyether adheres to strict quality management protocols to ensure batch-to-batch consistency and performance reliability. Each lot is characterized for critical parameters including fluorine content, hydroxyl value, and perfluoroalkyl chain distribution. Certificates of Analysis (COA) detailing purity, identity, and key physical properties are provided with every shipment to support 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 (15-25°C). Keep away from strong oxidizing agents and heat sources. Due to its light-sensitive nature, the container should be opaque or stored in dark conditions.
