Description

Bis[3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,11,11,12,12,13,13,14,14,15,15,16,16,17,17,18,18,18-Tritriacontafluorooctadecyl] Hydrogen Phosphate is a high-performance fluorinated phosphate ester surfactant, distinguished by its exceptionally long perfluoroalkyl chains. This structure is critical for delivering unparalleled surface tension reduction and exceptional chemical and thermal stability in demanding environments. It is an essential material for advanced material science and high-tech manufacturing sectors requiring superior hydrophobic, oleophobic, and release properties.

Application

• Fluorinated Surfactant & Leveling Agent: A key additive in high-performance fluoropolymer coatings, paints, and inks to enhance wetting, leveling, and substrate adhesion.
• Oil & Water Repellent Treatments: Used in the formulation of durable finishes for textiles, leather, paper, and non-woven fabrics to impart stain resistance.
• Release Agent & Mold Lubricant: Provides excellent non-stick properties in plastic, rubber, and composite molding processes, and as a component in mold release formulations.
• Fire-Fighting Foam (AFFF) Component: Serves as a critical fluorosurfactant in aqueous film-forming foam concentrates for hydrocarbon fuel fires.
• Electronic & Semiconductor Industry: Used in specialty cleaning agents and as an anti-foaming agent in chemical mechanical planarization (CMP) slurries.
• Lubricant & Anti-corrosion Additive: Incorporated into high-end greases and lubricants for extreme pressure and corrosion-resistant applications.
