ColorMount is not considered to be an archival material.
BufferMount is the
archival stuff---neutral pH and it is possible to reverse
the mounting
process with BufferMount, although not with the greatest of
ease.
BufferMount sets after the print/tissue/board assembly is
removed from the
press during cooling, necessitating firm and even pressure
for several
minutes as it cools. ColorMount, I¹m pretty sure, bonds in
the heat of the
press.

I'm not sure Color Mount is not archival, the
information should be available from whoever Seal is now.
All the thermosetting mounting materials stay plastic until
cooled. That's why the flat weight is important. Ideally it
should be of a highly heat conducting material like aluminum
but even plywood will do if you leave the print sandwich
long enough. It should also be fairly heavy. Seal used to
sell a weight made of thick sheet aluminum with a couple of
handles on one side but its easy enough to make one.
Much of my procedure came from an old Seal manual, long
out of print, added to my personal experience in dry
mounting.
