Non Stick Ceramic Coating Composition And Process

The ceramic cookware coating maintains its prominence amongst other types of non stick pans owing to its nobility.

Non stick ceramic coating composition and process. 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. A non stick coating composition according to claim 1 wherein the matrices are comprised of from 30 wt to about 70 wt of silica sol and 2 wt to 40 wt of methyltrihydroxysilane. A non stick surface is a surface engineered to reduce the ability of other materials to stick to it. The inorganic composition makes ceramic coatings environment friendly.

And actually ceramic nonstick pans are less nonstick y than regular nonstick ones. Ceramic coatings are hence inorganic in nature primarily containing silicon and oxygen and necessarily no carbon. 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. A non stick coating composition according to claim 1 wherein a catalyst is present in an amount up to about 2 wt of the matrices.

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. Ceramic coating is a newer idea in the world of non stick cookware and has been introduced in recent years by different brands. Ceramic coatings are essentially made of hardened clay and are completely free from ptfe and other chemicals. Non stick is often used to refer to surfaces coated with polytetrafluoroethylene ptfe a well known brand of which is teflon in the twenty first century other coatings.

Two kinds of non stick organic compounds make a chemical bond with silica ceramic network or matrix and it can exist in the ceramic structure in a stable state. The ceramic non stick hybrid coating is applied by a 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.

Non stick cookware is a common application where the non stick coating allows food to brown without sticking to the pan. A method of making 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.
