Liquid silicone

Silicone is an inorganic polymer composed of silicon and oxygen atoms. Its use is highly widespread as a non-stick coating for trays and metal moulds in the food sector, especially in baking industry, as it is inert and stable.

It has a liquid form, and it is sprayed onto the parts to be coated. It eventually polymerises, adopting its usual appearance, after being thermally treated. Most common silicones used in the food sector are red and black, although some of them are grey and blue.
