Sika Aktivator-205 (Sika Cleaner-205) 250ML

Description

Transparent solvent-based adhesion promoter for non-porous substrates
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 / adhesives. Sika® Aktivator-205 is designed for the treatment of bond faces prior to application of Sikaflex® and Sikasil® adhesives and sealants.

Enhanced adhesion on various substrates
Short flash-off time
Easy to use

METHOD OF APPLICATION
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.

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.
