Sika Aktivator-205 Adhesion Promoter 250ml Clear

The Sika Aktivator-205 is a solvent-based, colourless clear adhesion promoter designed to significantly enhance the bond between substrates and primers, sealants, or adhesives. When applied, it reacts with moisture to deposit active groups on the surface, creating a strong chemical link that improves adhesion on non-porous materials.

This activator is specifically formulated for use prior to the application of Sikaflex® and Sikasil® adhesives and sealants. It is ideal for improving adhesion on challenging surfaces such as metals, plastics, ceramic screen prints, and painted surfaces. With its short flash-off time, it allows for efficient workflow and easy application.

Applications

• Ideal for non-porous substrates like metals, plastics, ceramics, and painted surfaces
• Use before applying Sikaflex® or Sikasil® adhesives and sealants
• Recommended for bond face treatment in various assembly and repair tasks
