Non-stick coating refers to the coating formed after coating with low surface energy, easy to clean and other characteristics of the coating, which is widely used in all kinds of food contact, hardware products, mechanical parts, chemical equipment, electrical equipment.

Non-stick pans are also the most widely recognized non-stick paint application scenarios.

1, non-stick coating has fluorine resin system, silicone system, ceramic system three mainstream products.

At present, the non-stick coatings on the market are mainly divided into fluorine resin non-stick coatings, silicone non-stick coatings and ceramic non-stick coatings, among which fluorine resin non-stick coatings are the mainstream, fluorine resin non-stick coatings can be divided into polyimide binders and polyaryl ether binders according to the differences in binders. In the future, polyaryl ether binders will be the direction of technological evolution. According to the type of solvent, it is divided into water-based non-stick coating, oily non-stick coating, powder non-stick coating, and water-based non-stick coating is the mainstream at present.

2, fluorine resin non-stick coating: performance "unique", generally need special engineering plastics as adhesive use.

Fluorine resin non-stick coating is usually PTFE based PTFE, PFA, FEP three mixture of the form exists, binder to polyimide, polyaryl ether two types of special resin based, coating performance to composite multi-coating is best, fluorine resin non-stick coating has the best non-stick and comprehensive protection effect, in addition to the field of kitchenware and home appliances has a better application, Fluorine resin non-stick coatings can also be widely used in harsh acid, alkali, salt, high temperature protection, lubrication requirements, such as chemical reactors, large industrial nuts and bolts.

However, due to the high melting point of fluorine resin and adhesive resin, the coating film baking temperature is high and the energy consumption is large, the adhesive resin is difficult to water-based processing and high energy consumption, and it is difficult to avoid the use of high temperature solvent when baking film, which limits the further improvement of fluorine resin non-stick coating in environmental protection.

Fluorine resin PTFE, PFA, FEP are perfluoroppolymer, molecular chain structure due to C-F bond, its bond energy of 485kJ/mol, in all chemical bonds can be called the first, long-term use temperature 220℃, almost with all substances are not bonded, with excellent chemical stability, heat resistance, acid and alkali resistance, flame retardant, aging resistance and self-lubrication. Applied to non-stick coatings, in the range of cooking oil smoke temperature 180℃, fluorine resin structure is stable, safe and reliable, its low surface energy properties can effectively prevent food oil, protein and other materials adhesion and penetration, so it becomes the ideal choice for manufacturing non-stick coatings.
