Description

Bis(Eicosafluoroundecyl)Sulfate is a highly fluorinated anionic surfactant characterized by its exceptional chemical and thermal stability. This compound is valued for its powerful ability to dramatically lower surface tension, even in harsh environments, making it a critical performance additive. It is primarily needed by manufacturers in the specialty chemical, advanced materials, and electronics industries seeking to enhance the wetting, leveling, and anti-foaming properties of their formulations.

Application

• As a high-performance surfactant and wetting agent in fluorinated fire-fighting foams (AFFF).
• As a critical additive in the formulation of specialty coatings and paints to improve substrate wetting and leveling.
• As a processing aid and anti-foaming agent in the manufacture of fluoropolymers like PTFE and PFA.
• In the electronics industry for use in advanced etching and cleaning solutions.
• As a key ingredient in the synthesis of other perfluorinated compounds and surface modifiers.
• In research and development of novel materials requiring extreme surface activity and stability.

Quality Control

Our Bis(Eicosafluoroundecyl)Sulfate is produced under stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including assay, impurity profiling, and functional performance verification, to ensure it meets precise customer specifications. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and compliance.

Storage

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