摘要：Blended fluoropolymer compositions that, in one exemplary application, maybe applied as a coating to a substrate and, optionally, may be applied to a substrate thathas been previously coated with a primer or basecoat and/or a midcoat. In oneembodiment, the composition is a blend of at least one high molecular weight tracemodified polytetrafluoroethyelene (TMHPTFE) and at least one melt-processiblefluoropolymer (MPF). After being applied to the substrate, optionally over a primer orbasecoat and/or midcoat, and then cured, the present compositions form coatings thatdemonstrate improved abrasion resistance and/or improved release characteristicsand/or increased translucency/transparency and /or improved impermeability. Thepresent compositions may also be used to produce films having a high degree of clarityand impermeability. The present compositions in powder form may be melt or pasteextruded to form articles with improved impermeability.
