Glass Sealing Products

A variety of standard and custom Glass Transfer Tapes are manufactured by Vitta to fit a wide range of glass joining and sealing applications.

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 UK 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 designed to satisfy a wide range of applications. In addition to the standard tapes shown in the table below, we can also manufacture custom tapes from any glass frit available in the market today. All of our standard and custom tapes are available as preforms. By having the glass tape made to the exact size and shape needed, preforms can help speed up the production process and reduce waste.

Vitta has the experience and expertise to help you select the glass frit that is best suited for your application. Please contact us for further information.
