Ceramics, Silicon, Metals(SUS, Al, Hastelloy),
Coated products(Alumite, et al)
Case example of cleaning
Although it depends on types of film, deposits are capable of removal from deposited surface of ceramics and metal parts.
Cleaning methodology applied to do much less damage to base materials keeps the surface condition as it originally was
- Metals(SUS, Al, Hastelloy)
- Coated products(Alumite, et al)
Quartz surface treatment with plasma-resistance
CVD Yttria is a transparent protection film which features excellent plasma-resistance property.
CVD Yttria is an adhesive, scrupulous type of film, so is very effective as a protection film applied to window products, used in plasma-treated process using CI and F gases.
Fluorocarbon resin coating
Techno Quartz is capable of coating quartz substrate with high-purity PFA, which provides excellent performance in heat resistance, chemical resistance, and abrasion resistance
- Contained particles, and reduced contamination
- Excellence in chemical resistance, heat resistance,
and abrasion resistance
- High adhesion
- Reproducing coating layers
Case example of PFA coating:
PFA coated on quartz substrate
Cutting-edge technology of part tracing technology
Graphic character codes such as QR codes or barcodes, through which Handy Terminal or barcode reader recognizes part# and serial# and so on, are laser-engraved in the quartz body. They help to improve the accuracy of traceability controls and work efficiency.
According to applications, Techno Quartz is capable of laser-marking 1D/2D code, location alignment mark, or identification label into the quartz body.
Planar quartz substrate
Quartz tube substrate and cylindrical quartz substrate
Patent# 6412156: Product embedded with tracing information
Self-supported film with a porous structure
Manufacturing method of self-supported film in which porous coat gets detached from a substrate undamaged enables fabrication of porous structure made of ceramics and metals with high melting points to cost less.
This feature is effective in larger surface areas, heat insulation, and lightweight where porous characteristics are taken advantage of.
Patent# 5849083: Manufacturing method of porous structure and self-supported film
