Transparent, solvent-based adhesion promoter for non-porous substrates
Sika Aktivator-205 is a solvent-based, colourless, 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 is designed for the treatment of bond faces prior to application of Sikaflex and Sikasil adhesives and sealants.
