Siltorr is a bakeable high vacuum leak sealant developed for the express purpose of sealing small high vacuum leaks while under operating conditions or
where exposure to high bakeout temperatures is likely to follow. It may also be used as a general vacuum leak sealant through cryogenic temperatures.
Siltorr may be applied to any component material such as glass, metal or ceramic or any combination of these. When properly used it will create a
permanent inconspicuous seal.
Its maximum useful temperature depends somewhat on the size of the leak but in most cases bakeout temperature up to 4000C may be reached.
Vapor pressure at room temperature is less than 10-9 torr.
