B) for specific application, temperature and flash-off time may be different C) stored in sealed container in a dry place at < 25 °C Primer Product Benefits ■ Enhanced adhesion on various substrates ■ Short flash-off time ■ Easy to use ■ Transparent DESCRIPTION Sika® 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. Sika® Aktivator-205 is designed for the treatment of bond faces prior to application of Sikaflex® and Sikasil® adhesives and sealants. AREAS OF APPLICATION 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 cracking. 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.

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