Sikaflex®-668
High-performance assembly, glazing adhesive and sealant with acceleration option
Sikaflex®-668 is based on Purform®, a polyurethane with less than 0.1% monomeric diisocyanate for better health protection and occupational safety. The Sikaflex®-668 adhesive system is specifically designed for the rail industry. It is suitable for assembly bonding and glazing applications. Its weathering and unique resistance to a wide variety of cleaning agents makes it a very good solution for use in exterior joints. Sikaflex®-668 is compatible with Sika’s black-primerless bonding process. Sikaflex®-668 can be accelerated with Sika’s Booster and PowerCure system.
