■ Product content and main applications

Product content
A clear and colorless product in which OPTIC ARMOR is molded into a ring shape with an O-shaped cross section. Low discharged gas grade.
Main applications
Exceptional purity due to our own mixture design and packaging specification. It has excellent non-adhesive characteristics against metals, and it is used for exposure equipment, etc. that is incompatible with discharged gas.
