Description

Potassium Perfluorooctanoate is a highly fluorinated anionic surfactant known for its exceptional stability and surface activity. This compound is valued for its ability to dramatically lower surface tension in aqueous and organic systems, even at very low concentrations. It serves as a critical processing aid and performance additive in advanced manufacturing, particularly within the fluoropolymer and specialty chemical industries.

Application

• As a critical emulsifier and surfactant in the aqueous emulsion polymerization of fluoropolymers like PTFE (Teflon®) and PFA.
• As a wetting and leveling agent in high-performance coatings, inks, and fire-fighting foams (AFFF).
• As a processing aid for enhancing the dispersion and stability of fluorinated compounds in various formulations.
• In the production of fluorinated surfactants and intermediates for specialized chemical synthesis.
• As a surface treatment agent for textiles, leather, and paper to impart oil, water, and stain resistance.
• For research and development in material science, particularly in creating superhydrophobic and oleophobic surfaces.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from strong acids and strong oxidizing agents. This material is hygroscopic (moisture-sensitive); ensure containers are sealed after each use to prevent absorption of atmospheric moisture.
