摘要： Blended fluoropolymer compositions are provided. In one embodiment, a liquid dispersion of a first fluoropolymer is blended with a liquid dispersion of a second fluoropolymer. The first fluoropolymer may be polytetrafluoroethylene (PTFE), such as a low molecular weight PTFE (LPTFE) that has been polymerized via a dispersion or emulsion polymerization process, and which has not been agglomerated, irradiated, or thermally degraded. The LPTFE may be in the form of an aqueous dispersion, having a mean particle size of less than 1.0 microns (μm), with the LPTFE having a first melt temperature (Tm) of 332° C. or less. The second fluoropolymer may be a melt processible fluoropolymer (MPF), such as methylfluoroalkoxy (MFA), fluorinated ethylene propylene (FEP), or perfluoroalkoxy (PFA), for example, in the form of an aqueous dispersion, and having a mean particle size of less than 1.0 microns (μm). Blending of the dispersions facilitates interaction of the LPTFE and MPF on a submicron level to facilitate intimate blending such that, when the blended fluoropolymer composition is dried, a crystal structure representing a true alloy of the fluoropolymers is formed, having melt characteristics that differ from those of the individual fluoropolymers. The blended fluoropolymer composition may be used to provide a coating having improved impermeability, stain resistance, abrasion resistance, smoothness, and higher contact angles.

摘要： A fluoropolymer coating composition that may be applied over a primer and/or at least one midcoat in a non-stick coating system. The coating composition may be prepared and applied in the form of a liquid dispersion, and includes at least one fluoropolymer base component, such as polytetrafluoroethylene (PTFE) and, in particular, at least one high molecular weight PTFE (HPTFE). The coating composition additionally includes a blended fluoropolymer composition. The blended fluoropolymer composition is a blend of at least one low molecular weight PTFE (LPTFE) and at least one melt-processible fluoropolymer. After application directly to a substrate or over an underlying coating, the coating demonstrates improved abrasion and scratch resistance, as well as improved release characteristics, as compared to known coatings that include only HPTFE or HPTFE with a small amount of melt processible fluoropolymer.
