Assembly & glazing adhesive and sealant for rail applications with acceleration option
Sikaflex®-268 is an adhesive system specifically designed for the rail industry. It is suitable for assembly bonding and glazing applications; its outstanding weathering resistivity and unique resistance to a wide variety of cleaning agents make it an ideal solution for use in exterior joints in the rail industry. Sikaflex®-268 is compatible with Sika’s black-primerless bonding process. Sikaflex®-268 can be accelerated with Sika’s Booster and PowerCure systems.
Sikaflex®-268 is designed for large-component-assembly and direct-glazing applications in the rail 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. Seek manufacturer’s advice and perform tests on original substrates before using Sikaflex®-268 on materials prone to stress cracking. Sikaflex®-268 is suitable for experienced professional users only. Test with actual substrates and conditions have to be performed to ensure adhesion and material compatibility.
