Fluororesin Coating 'HBA-838'

Explanation of Yoshida SKT's fluororesin coating 'HBA-838'.

There are various types of resin for fluoropolymer coatings, depending on the application environment. At Yoshida SKT, we specify materials and processing based on the product number. 'HBA-838' is a type of PFA coating. By processing it to a thicker film, it results in a coating without pinholes, making it suitable for applications that require corrosion resistance. 【What is PFA (Perfluoroalkoxyalkane Polymer)?】 PFA is an improved resin of PTFE, with the same continuous use temperature of 260°C. Its melting point is around 310°C, and it has a lower thermal melt viscosity than PTFE, allowing for a continuous film with fewer pinholes that could not be achieved with PTFE during coating. As a corrosion-resistant coating, it has the best performance among fluoropolymer coatings. Additionally, PFA can exhibit superior non-stick properties compared to PTFE depending on the substrate, making it widely used for non-stick and release coatings. *For more details, please download the materials or contact us.

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 does not stick or is difficult to stick. ■ Water and Oil Repellency It repels water and oil well when they come into contact with the surface, making it difficult for dirt to adhere and easy to clean. ■ 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 and exhibits excellent lubricity. ■ Chemical Resistance It is rarely affected or corroded by chemical agents 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 electrical breakdown), high volume resistivity, and high surface resistivity, demonstrating excellent electrical insulation properties.
