I will provide a detailed explanation of "Teflon / fluororesin coating," which is classified as resin coating within coating technology.
**Types and Characteristics of Coatings** ■ PTFE Coating The continuous use temperature is the highest at 260°C, and it excels not only in heat resistance but also in non-stick and low friction properties. ■ PFA Coating It has the same continuous use temperature of 260°C as PTFE. It has a low thermal melt viscosity and is used as an anti-corrosion coating and non-stick coating. ■ FEP Coating Its heat resistance is lower at 200°C compared to PTFE. It provides a smooth surface with fewer pinholes in the coating. **Characteristics of Coatings** ■ Non-Stick Property It has the property of not adhering or being difficult to adhere to strongly adhesive substances. ■ Water and Oil Repellency It repels water and oil well even when they come into contact with the surface. ■ Heat and Cold Resistance Among resins, it has high heat resistance and can withstand high temperatures (260°C). ■ Low Friction Property It is very slippery and has excellent lubricating properties. ■ Chemical Resistance It is rarely affected or corroded by chemical substances such as acids and alkalis. ■ Electrical Properties It has high insulation strength (resistance to electrical breakdown), volume resistivity, and surface resistivity, making it excellent in electrical insulation. *For more details, please download the PDF or contact us.*
