SikaFast®-3131S is a flexible, two-component acrylic adhesive with incorporated spacer shims (0.07 to 0.08 cm) designed
to maintain uniform bondline thickness. SikaFast®-3131S is designed to efficiently transfer high loads and evenly
distribute stresses. These characteristics distinguish SikaFast®-3131S from other acrylic adhesives that claim high strength
and elongation. SikaFast®-3131S bonds many materials without surface preparation or priming and cures rapidly at room
temperature.
