Sika Aktivator-100 is a solvent-based, colourless 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-100 is specially formulated for the treatment of bonding surfaces prior to the use of Sikaflex adhesives and sealants.

Sika Aktivator-100 is specifically formulated for adhesion improvement on substrates such as flat glass, ceramic-rimmed glass, on cut-off polyurethane adhesive beads and lacquers.

Features Sika Aktivator 100

  • Enhanced adhesion on a wide variety of non-porous substrates.
  • Short flash-off time.
  • Easy to use.
  • Transparent.

Instructions for use

Wipe bond faces with a clean, lint-free paper towel moistened (not wet) with Sika® Aktivator-100. Immediately wipe-off with a clean, dry, lint-free paper towel. 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. Sika® Aktivator-100 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 (59 °F and 77 °F). Consumption and method of application depends on the specific nature of the substrates. Tightly reseal container immediately after each use.
