  • FT-4800
  • What glue is used to bond piezo buzzer element? The glue applied to the piezo diaphragm on the security alarm is generally UV glue, but the glue combined with epoxy + acrylic acid comes out, which can replace UV glue with high toughness and can withstand 260 ℃ high temperature for 10 seconds and 120 ℃ for 90 min It is a kind of epoxy adhesive with high heat resistance, moderate curing strength, high impact resistance, and high humming resistance; It has toughness, impact resistance, displacement resistance and ultra-low linear expansion coefficient, excellent temperature resistance and simple operation.
