Description

Ammonium 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] Phosphate is a high-performance, fluorinated ammonium phosphate salt designed to impart exceptional surface properties. This compound is critical for applications demanding extreme hydrophobicity, oleophobicity, and chemical resistance due to its long perfluoroalkyl chains. It is primarily sought by formulators and manufacturers in the specialty coatings, advanced materials, and surface treatment sectors.

Application

• As a key additive in oil- and water-repellent textile finishes for protective clothing and outdoor gear.
• In the formulation of anti-fingerprint and anti-smudge coatings for electronic displays and touchscreens.
• As a surface modifier to create superhydrophobic and self-cleaning coatings for architectural glass, solar panels, and automotive surfaces.
• In the production of high-performance fluorosurfactants and leveling agents for demanding industrial coating systems.
• As a processing aid or release agent in the manufacture of specialty polymers and composites.
• For imparting stain and soil resistance to carpets, upholstery, and paper products.
