Storage and Handling of Dispersions

Microscopic examination of PTFE dispersion can reveal coagulation of particles. Under magnification, numerous white lumps indicate coagulation or spoilage of the dispersion. A normal dispersion, while it may contain an occasional coagulum, appears uniform and free of lumps. 

Polytetrafluoroethylene dispersions may contain one or more surfactants (and other additives) such as perfluoroammoniumoctanoate, also known as C8 in parlance of the industry. There are health hazards associated with some of the surfactants such as C8.
