Solvent-based adhesion promoter for non-porous substrates
Sika® Aktivator-205 is a clear, solvent-based adhesion promoter that 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 surfaces to be bonded before the application of Sikaflex® and Sikasil® adhesives and sealants.
Uses
Sika® Aktivator-205 is used to improve adhesion on non-porous substrates such as metals, plastics, ceramic screen prints, and painted surfaces. Ask the manufacturer for advice and perform tests on original substrates before using Sika® Aktivator-205 on stress-cracking-prone materials. This product is only suitable for experienced professional users. To ensure adhesion and material compatibility, tests should be performed with the substrates under real conditions.
