SikaFast 3121 is a fast-curing, two component flexible adhesive for applications requiring quick fixturing for higher throughput. Like other SikaFast-3000 adhesives, 3121 is designed to efficiently transfer high loads and evenly distribute stresses. These characteristics distinguish SikaFast 3121 from other acrylic adhesives that claim high strength and elongation. SikaFast 3121 bonds many materials without surface preparation or priming and cures rapidly at room temperature. (Mixing nozzles not included.)

SikaFast 3121 is a 10:1 two part structural adhesive designed to substitute or complement welding, riveting, clinching and other mechanical fastening techniques used in the manufacture of transportation vehicles. SikaFast-3121 is suitable for bonding sidewall panels; roofs, floors and parts made of aluminum, stainless or galvanized steel and fiber reinforced polymers.
