Usage
Sikaflex®-268 PowerCure is designed for assembly and direct-glazing applications in rail, the commercial vehicle industry and for the repair market. It exhibits excellent tooling and application properties. With its superior resistance to a wide range of cleaning agents combined with outstanding weathering resistance, it can be used for exterior joints. Curing of Sikaflex®-268 PowerCure is accelerated by Sika’s PowerCure technology which makes it largely independent of atmospheric conditions. Seek manufacturer’s advice and perform tests on original substrates before using Sikaflex®-268 PowerCure on materials prone to stress cracking. This product is suitable for professional experienced users only. Tests with actual substrates and conditions have to be performed ensuring adhesion and material compatibility.
