Hi Richard:
After replacing over 200 sets of keytops, I have settled on solvent
based contact cement. Water base doesn't hold well which might explain the
failures. That doesn't mean there aren't good alternatives, PVC-E works
well too, but there's some drying time involved. There are pros and cons to
all adhesives, one could go into quite a dissertation on just keytop glues
and what form they take i.e., spray, gel, or liquid.
