Does PVC-E work equally as well on plastic sharps? I found only one reference in the archives. Thanks, Dave Davis Renton, WA Was the old "pyralin glue" that Schaff or American used to sell = for keytops the same as PVC-E? It worked pretty well, as I remember, = but didn't have a long shelf life -- hardened into one rubbery blob. = Smelled like Duco Cement. Anyway, it's not in the catalog now, and = PVC-E seems to be what they recommend for plastic (or ivory?) keytops. And what is "pyralin" anyway -- just a type of plastic? I know = from (bad) experience, that when gluing keytops with the wafers and = brass plates, then heating them [I was taught to put a little blob of = Sterno on the plate, then light it. It burns for a minute or so, then = goes out, and the ivory and wafer bonds quite well to the key], if you = accidentally spill Sterno juice on the key front or heat the key front = too hot with a heat gun, it will flame up and burn faster than a = marshmallow over a campfire! And I'm wondering if "pyralin" has = anything to do with "pyro" or if heat or fire is used in its = manufacture, or what? =20 I always thought (old) plastic keytops, and especially key fronts, = were celluloid, and that's why they burn so easily, like old movie film. = =20 --David Nereson, RPT=20 ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
