Description

Diammonium 3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,10-Heptadecafluorodecyl Phosphate is a specialized fluorinated surfactant and surface modifier, distinguished by its unique perfluorinated alkyl chain linked to a phosphate diester ammonium salt. This molecular structure provides exceptional surface tension reduction, chemical resistance, and oil/water repellency, making it a critical performance additive. It is primarily utilized in industries requiring durable, low-surface-energy coatings and treatments. Key applications include advanced textile finishing, high-performance polymer processing, and specialized fire-fighting foams.

Application

• Textile & Fiber Treatment: As a durable water and oil repellent (DWR) finish for technical fabrics, outdoor apparel, and upholstery.
• Fluoropolymer Processing Aid: Acts as a surfactant and release agent in the polymerization and processing of PTFE, PVDF, and other fluoropolymers.
• Fire-Fighting Foams (AFFF): A key fluorosurfactant component in aqueous film-forming foams for rapid fire suppression of flammable liquid fires.
• Paper & Packaging Coatings: Imparts grease resistance and moisture barrier properties to specialty papers and food packaging.
• Leather & Non-Woven Finishing: Provides stain and soil resistance for high-end leather goods and technical non-woven materials.
• Performance Coatings & Paints: Used as a flow control and leveling agent to improve surface properties and chemical resistance in industrial coatings.
• Electronic Materials: Serves as an additive for anti-fingerprint and anti-stain coatings on electronic device surfaces.

Quality Control

Our production of Diammonium 3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,10-Heptadecafluorodecyl Phosphate adheres to a strict quality management system. Every batch undergoes rigorous analytical testing to ensure consistent purity, chemical identity, and performance characteristics. Key parameters such as assay, fluoride content, and pH are monitored. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with each shipment to guarantee traceability and compliance with your specifications.

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 material is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which may affect product performance.
