Description

Diammonium 3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,11,11,12,12,13,13,14,14,15,15,16,16,16-Nonacosafluorohexadecyl Phosphate is a specialized fluorinated phosphate ester salt, distinguished by its long perfluoroalkyl chain which imparts exceptional surface-active properties. This compound is engineered to deliver superior performance as a durable water and oil repellent and leveling agent in high-performance coatings and textiles. It is a critical raw material for manufacturers in the technical textiles, specialty polymers, and advanced material coatings sectors, where long-lasting fluorochemical functionality is required.

Application

• Fluorinated Surfactant & Leveling Agent: Used in high-performance fluoropolymer coatings and paints to improve wetting, leveling, and film formation.
• Durable Water & Stain Repellent (DWR): A key ingredient for treating technical textiles, outdoor apparel, upholstery, and carpets to provide long-lasting protection.
• Paper & Packaging Coatings: Imparts oil and grease resistance to food packaging, release papers, and specialty paper products.
• Fire-Fighting Foam Concentrates (AFFF/FP): Acts as a fluorosurfactant component in formulations designed for liquid fuel fires.
• Mold Release Agents: Used in polymer processing and composite manufacturing to facilitate clean part release.
• Electronics & Semiconductor Industry: Employed in anti-fingerprint coatings and as an additive for fluorinated electronic chemicals.
• Leather & Synthetic Leather Treatment: Provides stain and water resistance while maintaining breathability.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product performance.
