Sika Cleaner (1LT)


Sika® Aktivator-205 is a solvent-based colorless 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 /
Sika® Aktivator-205 is designed for the treatment of bond faces prior to application of
Sikaflex® and Sikasil® adhesives and sealants.

Sika® Aktivator-205 is used to improve adhesion on non-porous substrates such as
metals, plastics, ceramic screen prints and
painted surfaces.
Seek manufacturer’s advice and perform
tests on original substrates before using Sika®
Aktivator-205 on materials prone to stress
This product is suitable for experienced professional users only. Tests with actual substrates and conditions have to be performed
to ensure adhesion and material compatibility

Surfaces must be clean, dry and free from
grease, oil, dust and contaminants.
Adhesion on substrates may be improved by
adding and/or combining pre-treatment processes such as scuffing and cleaning prior the
activator application.

Wipe bond faces with a clean, lint-free paper
towel moistened (not wet) with Sika® 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.
Sika® 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.
