Description

Pentanoic Acid, 4,4-Bis(.Gamma.-.Omega.-Perfluoro-C8-20-Alkyl)Thio Derivs., Compds. With Diethanolamine is a specialized fluorinated surfactant and surface-modifying agent. This compound is engineered to deliver exceptional oil, water, and stain repellency, as well as low surface energy properties, making it a critical performance additive. It is primarily needed by formulators in the coatings, textiles, and advanced material sectors seeking to enhance the durability and functionality of their products.

Application

• As a key additive in fluorinated water and oil repellent finishes for textiles, leather, and non-woven fabrics.
• As a surface modifier and leveling agent in high-performance fluoropolymer coatings and paints to improve substrate wetting and film formation.
• In the formulation of specialty cleaning products and polishes to provide durable stain and soil release properties.
• As an additive for paper and packaging coatings to impart grease resistance and barrier properties.
• For surface treatment of fillers and pigments to improve dispersion and compatibility in polymer matrices.
• In the development of fire-fighting foams (AFFF) and other fluorosurfactant-based formulations, subject to applicable regulatory compliance.

Quality Control

Our production of this fluorosurfactant adheres to strict quality management systems. Every batch undergoes comprehensive analysis to ensure consistency in critical parameters such as fluorine content, active matter, and ionic character. Certificates of Analysis (COA) detailing purity, assay, and specific performance tests are available upon request to support your quality assurance and regulatory documentation 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). Keep away from strong acids, strong bases, and strong oxidizing agents. Due to the chemical nature of perfluoroalkyl substances, appropriate containment measures should be in place to prevent environmental release.
