Abstract:
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.
