Low Acoustic Loss Resin
If you repair a broken bell with conventional adhesive it will have terrible acoustic loss - it will sound like wood, not metal. If you repair with acoustobond it may still ring perfectly!
Acoustobond is refined, natural, thermo-setting resin with acoustic loss ~0.001. Acoustobond is hard and brittle at room temperature (and below), but melts at ~ 80ÂșC. It is easy to use.
