Description

 

Perfluorooctanesulfonic Acid is an anthropogenic fluorosurfactant and global pollutant. It is an exceptionally stable compound in industrial applications and in the environment because of the effect of aggregate carbon–fluorine bonds. Perfluorooctanesulfonic Acid is a fluorosurfactant that lowers the surface tension of water more than that of hydrocarbon surfactants.It's compounds can also be found in some impregnation agents for textiles, paper, and leather; in wax, polishes, paints, varnishes, and cleaning products for general use; in metal surfaces, and carpets.In the semiconductor industry, Perfluorooctanesulfonic Acid is used in multiple photolithographic chemicals including: photoacid generators (PAGs) and anti-reflective coatings (ARCs).
