Explanation of Yoshida SKT's fluororesin coating 'QCE-033M'.
There are various types of resin for fluoropolymer coatings, depending on the application environment. At Yoshida SKT, we specify materials and processing according to the product number. 'QCE-033M' is a type of PFA coating. Among fluoropolymer coatings, it is characterized by excellent non-stick properties, smoothness, and minimal defects. 【What is PFA (Perfluoroalkoxy Alkane Polymer)?】 ■Features It is an improved resin of PTFE, having the same continuous use temperature of 260°C as PTFE. With a low thermal melt viscosity, it can achieve a continuous film with fewer pinholes than PTFE, making it the highest-performing fluoropolymer for corrosion-resistant coatings. Additionally, PFA is superior in non-stick properties compared to PTFE for certain applications, and is used as a high-temperature release coating.

basic information
- Teflon(TM) Coating: Functions and Effects of Fluororesin Coating ■ Non-stick Property It has excellent release properties against strongly adhesive substances, meaning it either does not adhere or adheres very weakly. ■ Water and Oil Repellency It repels water and oil well when they come into contact with the surface. Therefore, it is difficult for dirt to stick, and it can be easily cleaned. ■ Heat and Cold Resistance Among resins, it has high heat resistance, enduring high temperatures (up to 260°C). It also withstands low temperatures down to -260°C. ■ Low Friction It has a slippery surface with a low friction coefficient. Additionally, it exhibits excellent lubricity. ■ Chemical Resistance It is rarely affected or corroded by chemical substances such as acids and alkalis. While a thin coating is not compromised, chemicals and solutions can penetrate the coating and corrode the substrate, so a thicker coating is applied to prevent substrate corrosion. ■ Electrical Properties It has high dielectric strength (the strength against dielectric breakdown), volume resistivity, and surface resistivity, making it excellent in electrical insulation.
