Thanks. Can you tell me more about its properties after curing? Right now, I'd love to make a custom earpiece for my smartphone - something I've done with Sugru in the past. It needs the material to be relatively rigid yet pliable after curing. It also needs to be sticky enough to bond to the phone case (I don't bond them to the phone glass anymore). Thank you!
