UV-curable adhesives

Adhesives that cure rapidly when irradiated by ultraviolet and are suitable for fixing and lamination of high-precision components.

  • Product name
    SA1000 series
  • Features
    • Having an acrylic and an epoxy types, suitable for the fixing of parts of optical pickups.
    • Features high UV-curing reactivity and the ability to cure rapidly.
    • The acrylic-type resin, SA1641SN, enables realization of high adhesion strength and is suitable for fixing laser diodes (LD) such as optical pickups.
    • The epoxy-type resin, SA1801SN, enables realization of high-precision fixing due to low cure shrinkage as well as good workability due to low tacking property on top.
