Description

Diammonium 3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,11,12,12,12-Icosafluoro-11-(Trifluoromethyl)Dodecyl Phosphate is a specialized fluorinated phosphate ester salt, designed to impart exceptional surface activity and chemical resistance. This compound matters for its ability to deliver high-performance, durable water and oil repellency, as well as outstanding stability in demanding environments. It is primarily needed by manufacturers in the textile, leather, and advanced materials sectors seeking to create high-value, functional finishes.

Application

• As a key fluorosurfactant and water/oil repellent agent in textile and fabric finishing.
• For imparting durable stain and soil resistance to carpets, upholstery, and technical fabrics.
• In the formulation of high-performance leather protectants and finishes.
• As an additive in coatings and paints to enhance surface properties and chemical resistance.
• For use in fire-fighting foams (AFFF) as a fluorosurfactant component (subject to regional regulatory compliance).
• In the production of paper and packaging to provide grease and moisture barriers.
• As a processing aid or surface modifier in advanced polymer composites.

Quality Control

Our production of this fluorinated phosphate ester adheres to strict quality management protocols. Each batch undergoes comprehensive analysis to ensure consistent performance and purity. A Certificate of Analysis (COA) detailing key parameters such as assay, fluoride content, and moisture level is provided with every shipment. We ensure compliance with relevant global chemical management frameworks.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation. Keep away from strong alkalis and incompatible materials.
