Abstract : The wear resistance of thin polymer coatings, e.g., pentaphthalic coatings PF-053 and PF-060, a Glyptal-resin export coating and cold and hot-hardening enamels PF-133, PF-115, and KF-243, were tested on an app. having a vibrating indenter. The shape (conical or cylindrical) and the area of the indenter affected the wear of the coating. The latter was proportional to the amplitude of the vibrations of the indenter. The experiments were best conducted at 200-800 Hz, since intensive wear showed reliable results in that frequency range. Hot-hardening alkyd resins (varnishes and enamels) showed superior wear resistance. (Author)
