Re: [ARSCLIST] Ampex & Sticky Shed Syndrome

["Peter@xxxxxxxxxxxxx" <lists@xxxxxxxxxxxxx>]

The problem of binder hydrolysis (sticky shed) is obviously, from the other
responses, not limited to a particular brand or a particular type of tape.
As this is an audio list, I thought I might add some additional information
from the video field that might not be as familiar to some of the list
members.

"Sticky shed" is quite common in the video tape field.  The most common
offenders are: Ampex 2", Memorex 2", 3M 2", Kodak 1", Fuji 1" (H621 only),
Sony 3/4" and Agfa 3/4".  It does appear in other tapes but less frequently
and is, usually, less severe.  Of course, if you expose any polyester tape
to enough moisture for a long time, you are likely to get binder hydrolysis.
