As a high-performance anti-stick material, silicone non-adhesive coating has been widely used in cooking utensils, molds and equipment in industrial production, etc.The following is an overview of the research on silicone non-viscose coatings：


1. Basic composition and structure
Silicone non-viscose coatings are usually composed of silicone resins, solvents, fillers and additives.Among them, silicone resin is the main component of the coating, which has excellent properties such as heat resistance, weather resistance, electrical insulation, hydrophobicity and chemical resistance.Solvents are used to adjust the viscosity of the coating to facilitate construction; fillers can enhance the hardness and wear resistance of the coating; additives are used to improve the processing performance and service performance of the coating.


The basic structural unit of silicone products is the silicon-oxygen link, and the side chain is a variety of organic groups connected to the silicon atom.This special structure makes the silicone material contain both "organic groups” and "inorganic structures", thus combining the characteristics of organic matter with the functions of inorganic matter.


Second, the principle of non-stick
The non-stick principle of silicone non-adhesive coating is mainly based on the following aspects：


High temperature stability: Silicone non-stick coatings have excellent high temperature stability and can maintain stable physical and chemical properties at high temperatures.This allows the coating to keep the surface smooth and non-sticky under high temperature conditions, and it is not easy to adhere to food or other substances.


Low surface energy: The surface energy of silicone non-stick coatings is low, making its surface not easy to adhere to other substances.This low surface energy can reduce the contact area between food or workpieces and the coated surface, thereby reducing the possibility of adhesion.


Chemical resistance: Silicone non-stick coatings have good chemical resistance, can resist the erosion of acids, alkalis and other chemicals, and are not prone to chemical reactions, so as to keep the surface smooth and non-sticky.


Wear resistance: Silicone non-stick coatings usually have certain wear resistance, which can reduce surface wear and maintain the flatness and non-viscosity of the coating.


Application areas and prospects
Silicone non-viscose coatings have been widely used in cooking utensils, molds and equipment in industrial production, etc.In terms of cooking utensils, silicone non-stick coatings can reduce friction and adhesion between food and pots and pans, thereby protecting the nutrients and taste of food.In industrial production, silicone non-stick coating can reduce the adhesion between the workpiece and the mold, improve production efficiency and product quality.
