Treatment of teflon to promote bondability



Various methods are reviewed whereby Teflon and other polyfluorocarbon resins can be surface treated in order to enhance their bondability with ordinary adhesives. The features of these methods are compared and some conclusions are drawn as to their relative usefulness. Particular emphasis is placed on the sodium-naphthalene-tetrahydrofuran treatment system and reference is made to a few military applications wherein sodium-treated Teflon has been employed.
