Abstract
Tough heat- and corrosion-resistant films of polytetrafluoroethylene (PTFE) are baked onto the surfaces of sheet-type gaskets in a curtain coating process. The gasket to be coated is passed through a flow of liquid PTFE-resin containing composition, the gasket inverted end-for-end, the opposite side coated, then baked, to form a tough film.
