Fluoropolymer-based coatings have a molecular structure made up of fluorine atoms and a long and straight saturated carbon. Due to the strong bonds between the atoms, this material is highly inert. With a low friction coefficient, fluoropolymers are resistant against abrasion and chemicals and therefore never stick on any substance. As they have higher heat resistance and can be processed in a wide range of temperatures compared to other polymers, fluoropolymers are frequently used in many industries.
Containing high-performance fluoropolymeric resin, . non-stick coatings are produced in spray form in accordance with international standards and can be used in cooking products and industrial kitchen equipment. . non-stick coating is applied directly on metal surface and then fired in high temperature in order to ensure that the coating sticks to the surface. After the firing, the coating creates a durable and non-stick surface.
Sol-gel process includes the formation of first colloidal suspensions of solid particles (sol) within a liquid phase and then 3D solid inorganic network structures (gel) in a constant liquid phase.

Today aluminum enamel is widely used in cooking materials such as pots, pans and cookers. As they can resist much higher temperatures compared to painted surfaces, they are also used in electrical household appliances reaching high temperature levels such as toasters, irons and ovens. Another area of use for enameled aluminum plates is construction industry where such plates are used in tunnels (as protection lines), warning signs and architectural panels (as decorative materials). In our country, the area of use for aluminum enamel is limited to cookware. In addition to heat resistance, this product is also advantageous in terms of weight. It is considerably lighter than equivalent steel materials.
Compared to steel alloys, aluminum alloys can be shaped more easily as their melting temperature is lower. These alloys are light. They not only transfer heat better and have higher specific heat, but also have the potential to expand and stretch more.
With very low melting temperatures, these frits soften at approximately 400 °C, boil at 550 °C, and have high expansion coefficient (approximately 450*10-7). As a result of these features, the most suitable enamels for aluminum are frits that are rich in alkali oxides.
