G'day Fooles...

We (Testing Branch of what was then Sydney County Council - now EnergyAustralia) found... accidentally in the process of a rush job on high voltage insulating sticks... that using "Superglue" (cyanoacrylate) instead of epoxy resin led to the safety shields shattering.

This is due to the cyanoacrylate's anaerobic setting, which leads to it expanding in those "micro-cracks". Fortunately, not many drinkers spike their beer with superglue...

Regards,

Bob
