Description

Ammonium Henicosafluorodecanesulphonate is a high-performance fluorinated surfactant and anionic perfluorinated alkyl substance (PFAS). This compound is valued for its exceptional ability to dramatically lower surface tension in aqueous and organic systems, providing superior wetting, leveling, and anti-foaming properties. It is a critical material for demanding industrial applications where extreme chemical and thermal stability are required, particularly in the electronics, coatings, and fire-fighting industries.

Application

• As a key surfactant and wetting agent in aqueous film-forming foam (AFFF) for fire-fighting applications.
• As a leveling and anti-cratering additive in high-performance industrial and specialty coatings, including paints and varnishes.
• As a surface treatment agent and emulsifier in the manufacture of fluoropolymer dispersions (e.g., PTFE, PFA).
• In electronics manufacturing for use in etching baths, photoresist developers, and cleaning solutions.
• As a critical component in oil and gas production for use in drilling muds and as a surfactant for enhanced oil recovery.
• In the formulation of polishing agents and cleaners for hard surfaces, providing superior stain resistance and sheeting action.

Storage

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