SikaFast®-3121 Flexible Adhesive
Available from Sika Corporation
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. 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.
