Abstract:
1. A dry melt flowable rotolining composition consisting essentially of particles of fluorine exposure-stabilized tetrafluoroethylene/perfluoro(ethyl vinyl ether) copolymer having an average particle size of about 100 to 3000 μm and sphere factor of less than 1.5 and 0.2 to 2 wt % of adhesion promoting, non-bubble promoting metal powder, the formation of said composition occurring after the fluorine exposure of said copolymer to obtain said fluorine exposure-stabilized tetrafluoroethylene/perfluoro(ethyl vinyl ether) copolymer, wherein, upon rotolining said composition on steel, the rotolined composition has an adhesion to said steel characterized by a peel strength of at least 25 lb/in.
