Description

3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,11,11,12,12,12-Henicosafluorododecyl Dihydrogen Phosphate is a highly fluorinated organophosphate surfactant and surface modifier. This compound is valued for its ability to impart exceptional oil, water, and stain repellency, as well as low surface energy properties to materials. It is a critical intermediate for manufacturers in the specialty chemicals, advanced materials, and performance coatings sectors seeking to develop high-value, durable surface treatments.

Application

• Fluorinated Surfactant & Leveling Agent: Used in high-performance coatings, inks, and polishes to improve wetting, flow, and leveling on difficult substrates.
• Textile & Fiber Treatment: Imparts durable water and oil repellency (DWR/DOR) to technical textiles, outdoor apparel, and carpets.
• Paper & Packaging Coatings: Provides grease resistance and barrier properties for food packaging and specialty papers.
• Surface Modification of Polymers: Acts as an additive or grafting agent to create low-surface-energy plastics and films for non-stick or release applications.
• Firefighting Foam Precursor (Legacy/Formulation): Historically used as a raw material or intermediate in the synthesis of certain fluorosurfactants for aqueous film-forming foams (AFFF).
• Electronics & Semiconductor: Employed in anti-reflective coatings and as a surface treatment agent for electronic components.
• Metalworking & Anti-corrosion: Used in formulations to create protective, hydrophobic layers on metal surfaces.
• Research & Development: Serves as a key building block for synthesizing novel fluorinated compounds in academic and industrial R&D.
