SikaFast®-3121 is a fast-curing, flexible, two-component acrylic adhesive for applications requiring quick fixturing for higher through-put. Like other SikaFast®-3000 series adhesives, SikaFast®-3121 is designed to efficiently transfer high loads and evenly distribute stresses. These characteristics distinguish SikaFast®-3121 from other acrylic adhesives that claim high strength and elongation. SikaFast®-3121 bonds many materials without surface preparation or priming and cures rapidly at room temperature.

  • High strength
  • Fast-setting and -curing
  • High elongation
  • High ductility
  • Good damping properties
  • Excellent adhesion to a wide variety of substrates with little or no surface preparation
