Abstract
A substrate is coated with a fluoropolymer non-stick coating comprising an undercoat and an overcoat, each containing fluoropolymer resin, said undercoat containing ceramic particles which extend from said undercoat, wherein said ceramic particles telegraph their presence through the overcoat, forming protrusions on the coating surface, to provide abrasion resistance to said coating by deflecting abrasion force away from the coating.
