P3D Mounting Adhesives and Slides

["Ivester, Paul" <ivestep@xxxxxxxxxxx>]

For 5 perf. slides I have been using the heat seal mounts, 
which I find to be quick and easy to use.  I use a very small 
homemade tacking iron to temporarily hold the edges of the 
film chips to the mount, and then seal the mount with an iron 
that I have modified by adding an aluminum plate in the shape 
of a stereo slide mount, with the areas of the film chips cut 
away.  

For 7 perf. slides I have been using the cardboard mounts made 
by Steve Spicer.  I find that taping the mounts is time 
consuming, and that a glued mount is stiffer.  I am now trying 
a new technique that I find works quite well for me.

This technique involves first spraying the slide mounts with 
3M mounting adhesive.  When spraying, I use a piece of 
cardboard to mask the area around the apertures so that there 
will be no adhesive touching the film, except at the edges 
outside the perforations.  I allow the adhesive to dry.  It 
will remain tacky for a few days, possibly longer.

I now place the film chips in half of a cutaway RBT mount, and 
check the alignment.  I then press the sprayed Spicer cardboard 
mount into contact with the film chip.  It will stick to the 
mount at the edges outside of the perforations.  I remove the 
RBT mount, and recheck the alignment.  I then fold the cardboard 
mount closed.  The adhesive sticks securely to itself.

This method seems very convenient, but I am concerned with the 
archival qualities of the adhesive.  Will the adhesive 
eventually destroy my film?  What do you think?
