FEP resin has the lowest critical surface tension among fluoropolymers (17.8 dyn/cm), making it difficult for liquids to wet the surface (i.e., it has high non-stick properties). Additionally, it has the lowest adhesion energy (42.0 dyn/cm), which means that even wetted liquids can easily detach (i.e., it has high release properties). For this reason, FEP resin is used in various fields, from molding molds for rubber and resin products like golf balls to molding shapes for solid propellant fuels in space shuttles and Ariane rockets, as well as in applications ranging from rolls to large paint mixing tanks. *For more details on non-stick and release coatings, please contact us or download our catalog for more information.*

Our "Peeling Static Electricity Prevention Coating" is designed to suppress peeling static electricity, particularly in the manufacturing processes of flat panel displays such as LCD and plasma displays, as well as LSI. For example, in the LCD manufacturing process, it suppresses the peeling static electricity that occurs when the glass substrate separates from the vacuum chuck plate, preventing damage caused by electrostatic discharge. This coating has the following three features: ● Peeling static electricity prevention performance ● Contamination-free ● High precision (ensuring flatness and parallelism) *For more details about the peeling static electricity prevention coating, please contact us or download the catalog to view it.

The characteristics of fluoropolymer, such as corrosion resistance and non-stick properties, are widely used as solutions to various challenges in different plants and manufacturing facilities. On the other hand, problems caused by static electricity charging on the surface of fluoropolymer are also frequently encountered. For example, it is well understood that the volume resistivity of glass lining is around 10^12 Ωm, and precautions against static electricity hazards are taken; however, there have been cases where the fact that the volume resistivity of fluoropolymer exceeds 10^16 Ωm has not been adequately considered. *For more details on static electricity prevention, please contact us or download our catalog for more information.*

In general, in fields centered around metals, the forms of wear are represented by the following four types: ● Adhesive wear ● Abrasive wear ● Corrosive wear ● Fatigue wear Additionally, secondary phenomena such as erosion, cavitation, and chipping are also noted. However, in the case of fluoropolymer coatings, this classification seems to be unsuitable, and based on various inquiries, it is considered to be represented by the following three types: ● Scratching wear ● Roughness wear ● Adhesive wear *For more details on wear-resistant coatings, please contact us or download the catalog for further information.*

For corrosion-resistant applications of fluororesin, there are broadly two categories: "sheet lining" and "baked coatings." In the case of sheet lining, a through-hole is created in part of the metal can body, allowing permeating substances that reach the metal to be released outside the system, thereby preventing extreme corrosion of the can body. In contrast, baked coatings differ in that they prevent the occurrence of corrosion by suppressing permeation. *For more details on corrosion-resistant coatings, please contact us or download our catalog for more information.*

To use fluororesin baked linings safely and for a long time, regular inspections are important. If you discover any abnormalities, please contact us. 【Points for Daily Inspection】 ■ Are there any scratches or cracks on the coating? ■ Is there any significant lifting of the coating? ■ Are there any blisters (small bulges)? ■ Is there any discoloration or fading? ■ Is there any wear on the coating? *For details on the maintenance guide, please contact us or download the catalog to view it.

The target of fluoropolymer coatings for semiconductor applications is primarily the components of semiconductor manufacturing equipment. The types of manufacturing equipment include cleaning devices, CMP devices, plating devices, transport and fixing applications, and exhaust and waste liquid systems. Fluoropolymer coatings are applied through melt bonding because they are thermoplastic resins. This means that the surface is leveled through melting, and there are virtually no gaps for particles to infiltrate. Similarly, the leveled surface maximizes the non-stick properties of the fluoropolymer, reducing the adhesion and carry-out of cleaning solutions, thereby increasing cleaning efficiency. From the above, we consider fluoropolymer coatings to be suitable surface treatments for cleaning devices. They are also actually used in various types of equipment. *For more details, please contact us or download and view the catalog.*

"Aμcoat" is a coating technology made from non-fluorinated resins that has a hard and non-rough surface, as well as high non-stick properties. While fluorinated resin coatings have excellent characteristics such as water repellency, corrosion resistance, and non-stick properties, issues may arise from the necessary high-temperature processing and distortion of the base material caused by shot blasting. "Aμcoat" is expected to solve these problems and provide applications that fluorinated resins cannot accommodate. 【Features】 ○ No need to strip the old coating during reapplication ○ Low-temperature firing below 200°C ○ No shot blasting required *For more details, please contact us or download the catalog to view.

"Aμcoat" is a coating technology of non-fluorinated resin that has a hard and non-pearled surface, as well as high release properties. While fluorinated resin coatings possess excellent characteristics such as water repellency, corrosion resistance, and non-stick properties, there are concerns about the high-temperature processing and distortion of the base material caused by shot blasting, which are essential for application. "Aμcoat" addresses these application issues and is expected to be applicable to base materials that cannot be treated with fluorinated resins. 【Features】 ○ High release properties and high hardness ○ Low-temperature firing below 200°C ○ No shot blasting required *For more details, please contact us or download the PDF for further information.
