Sika® Aktivator-205 LUM

Transparent solvent-based, detectable adhesion promoter for non-porous substrates

Sika® Aktivator-205 LUM is a solvent-based clear adhesion promoter which reacts with moisture and deposits active groups on the substrate. These groups act as a link between substrates and primers or sealants/adhesives. Sika® Aktivator-205 LUM is designed for the treatment of non-porous bond faces prior to the application of Sikaflex® and Sikasil® adhesives and sealants. Sika® Aktivator-205 LUM fluoresces under long-wave UV light for a limited period of time. This feature is used for in-process control.  

  • Enhanced adhesion on various substrates
  • Visible under UV-light
  • Short flash-off time
  • Easy to use
  • Transparent
