The invention provides for a substrate coated with a non-stick coating
which resists abrasion force, the coating comprising a fluoropolymer resin
containing ceramic particles to deflect the abrasion force away from the
coating wherein the ratio of the thickness of the coating to the longest
diameter of said ceramic particles is in the range of 0.8-2.0. Further,
the invention provides for a substrate coated with a non-stick coating
which resists abrasion force, the coating comprising an undercoat and an
overcoat, each containing fluoropolymer resin, the undercoat also
containing ceramic particles extending from the undercoat, the overcoat
telegraphing the particles extending from the undercoat through the
thickness of the overcoat to deflect the abrasion force away from the
coating. Preferably, the ratio of the combined thickness of the undercoat
and the overcoat to the longest diameter of the ceramic particles is in
the range of 0.8-2.0. The invention further comprises a composition
capable of forming an adherent coating to a smooth substrate and
exhibiting abrasion resistance, comprising fluoropolymer, polymer binder
and inorganic filler film hardener, wherein at least 30 wt % of the film
hardener is comprised of large ceramic particles having an average
particle size of at least 14 micrometers. Preferably the amount of ceramic
particles is sufficient to provide at least 3 such particles per 1 cm
length of transverse cross section of coating formed from said
composition.
