Keytop Adhesives

[Mark Story]

I don't care for spray adhesive because it's harder to clean up the
overspray.  I have used water-borne latex contact cement for many years with
good results. I think it's properties are similiar to PVCE, except that you
coat both surfaces (I use a miniture roller) and let it set up before you
assemble.  I think water-borne contact cement has gotten a bad rap at times
because it hasn't been used properly.  You _must_ allow both surfaces to set
up till they are clear before assembling.  Also, it's not very good if your
working environment is humid.

The last time I went to replenish my stock they didn't have my old reliable,
but had a product that is more rubbery.  It works fine, but is harder to
clean off your tray and roller - you must use a detergent with your wash
water.
