Description

Diammonium 2-[Ethyl[(Pentadecafluoroheptyl)Sulphonyl]Amino]Ethyl Phosphate is a specialized fluorinated surfactant and phosphate ester salt, engineered to deliver exceptional surface activity and stability in demanding environments. This compound is valued for its unique ability to dramatically lower surface tension and provide durable water, oil, and soil repellency. It is a critical performance additive for industries requiring advanced surface modification, including high-performance coatings, fire-fighting foams, and specialty textile treatments.

Application

• Fluorinated Fire-Fighting Foams (AFFF/AR-AFFF): A key ingredient in aqueous film-forming foams, providing rapid film formation and fuel resistance for Class B hydrocarbon fires.
• High-Performance Coatings and Paints: Imparts superior leveling, wetting, and anti-cratering properties, while enhancing water and oil repellency in industrial and architectural coatings.
• Specialty Textile and Leather Finishes: Used to create durable, breathable water and stain repellent finishes for technical fabrics, outdoor gear, and upholstery.
• Metal Treatment and Plating: Acts as a wetting agent and leveler in electroplating baths to improve surface uniformity and coating quality.
• Industrial Cleaners and Degreasers: Enhances the penetration and emulsification of oily soils in harsh, alkaline cleaning formulations.
• Paper and Packaging Coatings: Provides oil and grease resistance for food-contact paperboard and specialty packaging materials.
• Polymer Additive: Can be incorporated into polymers to modify surface properties and improve processing characteristics.

Quality Control

Our production of Diammonium 2-[Ethyl[(Pentadecafluoroheptyl)Sulphonyl]Amino]Ethyl Phosphate adheres to a stringent quality management system. Every batch is analyzed to ensure consistent chemical composition, purity, and performance characteristics. Certificates of Analysis (COA) detailing key specifications such as assay, fluoride content, pH, and moisture are provided and available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and incompatible with strong alkalis; keep the container tightly sealed to prevent moisture absorption and store away from incompatible materials.
