Smudge free graphite coated polymeric substrate and a method for preparing the same

摘要

A three component mixture of graphite, a liquid and a PTFE fine powder dispersion which has a homogeneous appearance and can be applied onto a substrate to provide a clean, glazed coating that does not easily shed graphite. Suitable substrates include: polytetrafluoroethylene filament; PTFE membrane; PTFE filament filled with graphite; polypropylene thread; polyaramide fibers.
