Abstract

Described herein is multilayer article made by the process comprising: delivering particles comprising a silicon compound from at least one fluid jet to a metal surface to embed the metal surface with the silicon compound to form a silicon compound layer; coating the silicon compound layer with an aqueous fluoropolymer dispersion to form a fluoropolymer layer and thereby forming a multilayered article, wherein the aqueous fluoropolymer dispersion comprises (i) a modifying agent; and (ii) a fluorinated polymer, wherein the fluorinated polymer comprises at least one of (a) a partially fluorinated polymer capable of forming a carbon-carbon double bond, (b) a functionalized fluorinated polymer, and (c) combinations thereof; and sintering the multilayered article to form the release surface coated substrate.
