Description

Bis[3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,11,11,12,12,12-Henicosafluorododecyl] Hydrogen Phosphate is a high-performance fluorinated phosphate ester surfactant, distinguished by its long perfluorinated alkyl chains which impart exceptional surface activity and chemical stability. This compound is critical for applications requiring extreme hydrophobicity, oleophobicity, and resistance to harsh chemical environments. It is primarily utilized by advanced material scientists and industrial formulators in sectors such as electronics, specialty coatings, and high-performance lubricants where standard surfactants fail.

Application

• Fluorinated Surfactant & Leveling Agent: Used in high-performance coatings, paints, and inks to improve wetting, leveling, and reduce surface defects on difficult substrates.
• Oil & Water Repellent Treatments: A key ingredient for imparting durable stain, oil, and water resistance to textiles, leather, and paper products.
• Electronics Industry: Employed as an additive in photoresists and electronic chemicals to control surface tension and ensure uniform film deposition during semiconductor manufacturing.
• Firefighting Foams (AFFF): Acts as a critical fluorosurfactant component in aqueous film-forming foams for combating flammable liquid fires.
• Specialty Lubricants & Release Agents: Provides superior lubricity and anti-stick properties in demanding industrial and molding processes.
• Polymer Additive: Used to modify surface properties of polymers, enhancing their anti-fog, anti-static, or release characteristics.
