NON-STICK CERAMIC COATING COMPOSITION AND PROCESS

摘要

The present invention provided non-stick ceramic coating compositions and methods for making same, and for coating utensils or cookware made of stainless steel, aluminum, aluminum alloy, cast iron or steel. A series of new non-stick ceramic coating materials prepared from organic-inorganic hybrid materials, including silica sol, MTMS, FAS and PDMS (Polydimethylsiloxane) using the sol-gel process. The hybrid materials have good mechanical properties and are fashioned into a main ceramic network and good non-stick properties from organic non-stick compounds. The non-stick ceramic coating consists of two layers applied to cookware and for other applications. The coating made by the novel non-stick coating composition can show a greater abrasion resistance, an increased surface hardness, and a longer wear.
