Abstract
Multiple coat non-stick coating systems, as well as articles coated with such non-stick coating systems, are provided. The primer () of the multiple coat system includes a fluoropolymer () copolymer, such as a fluoropolymer terpolymer including tetrafluoroethylene, hexafluoropropylene, and vinylidene fluoride monomers, which fluoropolymer copolymers are referred to collectively as THV. The multiple coat system exhibits excellent substrate adhesion and release properties, and the primer exhibits excellent primer-substrate adhesion and primer-topcoat adhesion. The multiple coat system is additionally resistant to separation failure at the interface between the binder () and fluoropolymer components of the primer, exhibits excellent adhesion to smooth substrates (), and may also include a high level of fillers to provide increased damage resistance without compromising the above benefits.
