DESCRIPTION
The SikaTack 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. SikaTack Aktivator 205 is designed for the treatment of bond faces prior to application of Sikaflex and Sikasil adhesives and sealants.
Once the SikaTack Aktivator 205 has been applied, it must be left for at least 10 minutes to dry. Once dried, the substrate will be ready for the second component of the panel fixing system which is the SikaTack Panel Primer.
Application
Wipe bond faces with a clean, lint-free paper towel moistened (not wet) with SikaTack Aktivator 205. Never dip the towel into the activator. Only wipe the surface with a clean side of the towel. Do not moisten the same paper towel twice and change it frequently.
SikaTack Aktivator 205 has to be applied sparingly as excess of activator could lead to adhesion failure. If the pre-treated area is not bonded within the maximum flash-off time, the activation process has to be repeated (once only). Ideal application and surface temperature is between 15°C and 25°C. Consumption and method of application depends on the specific nature of the substrates. Tightly reseal container immediately after each use.
