Abstract : The high fusing temperature required for producing Teflon coatings from aqueous dispersions has limited the applications to substrate materials capable of withstanding temperatures of around 750F. Resin-bonded Teflon coatings produced from thermosetting resins were found the most promising. Such coatings are most resistant to frictional welding, become harder as heating occurs, are unusually resistant to chemical attack, and are nonporous. The emulsion breakdown mechanism by means of which the dispersions in thermosetting resins are able to produce films with a Teflon-rich outercoat. (Author)
