SikaFast®-3121

Fast curing, 2-component toughened structural adhesive

SikaFast®-3121 is an acrylic based, fast curing, flexibilized structural, 2-component adhesive for applications requiring quick fixturing for higher throughput. It is designed to efficiently transfer high loads and evenly distribute stresses. SikaFast®-3121 provides very good adhesion on various substrates and is suitable to replace mechanical fixation.  

  • Strength development within minutes after application
  • Superior low-temperature flexibility compared to other structural adhesives
  • Adhesion to a wide range of substrates without or with limited surface preparation
  • High elongation and ductility
  • Good strength and impact resistance
