Just bought new tires and had Dyna Beads put in for balancing. I remember hearing that the beads come in a bag and it takes a while for the bag to disintegrate and release the beads. Is that correct ?...
I don't know what a Schrader valve is, but I had the beads put in my motorhome tires. They screwed up several of the tires and had to remount them. The first tire the guy tried to remount it with the loose beads still in the tire and the blew all over the place. He ended up vacuuming the remaining ones out and put a new bag of beads in.
