7 Claims

1. A coil-coated article, comprising

a substrate;

a coating disposed thereon at a film thickness of 0.5 to 1 mil and cured by baking for 8 to 25 seconds to a peak metal temperature (PMT) of about 200 to 250° C., the coating derived from a composition comprising:

a binder system including a first resin component comprising at least a fluoropolymer;

an organic filler material comprising polytetrafluoroethylene (PTFE) having a D₅₀particle size of about 7 to 12 μm;

about 1.5 to 10 wt %, based on the total weight of the composition, of an inorganic filler material comprising untreated amorphous silica and having a D₅₀particle size of about 5 to 15 μm; and

a liquid carrier,

wherein the coated article demonstrates damage tolerance of at least about 10,000 cycles at a coefficient of friction (μ) of no more than about 0.15.
