Sikaflex®-668 is based on Purform®, an industry-leading 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 outstanding weathering resistivity and unique resistance to a wide variety of cleaning agents make it an ideal 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.
