Glass-Transfer-Tapes

Glass Transfer Tapes are designed for coating or bonding a desired surface with a glass layer of a precisely known thickness and density. Glass transfer tapes consist of a highly flexible glass frit layer attached to a plastic carrier film. Some of the many applications for these tapes are; glass to glass or glass to metal seals, package sealing, protective coatings, assembly of optical cells, lasers, lamps, transducers, microwave components, vacuum devices, scientific glassware, and other optical and electronic systems. Glass Transfer Tapes not only replace liquid suspension techniques, direct fusing, and epoxies but also open the way for many new applications which might not be possible because of limitations with the old techniques.

Vitta Corporation pioneered the use of Glass Transfer Tapes more than 35 years ago. Over the years, Vitta has developed a series of Standard Glass Transfer Tapes
