ABSTRACT Adherent, PTFE coatings on polymer surfaces can be produced at temperatures well below the sintering temperature of PTFE, by contacting the surface with a dilute dispersion of PTFE particles and heating the surface to its softening point (in the vicinity of its glass transition temperature) to dry it and to cause the individual particles to become embedded in and surrounded by the polymer.
