SikaFast®-3121 is a fast-curing, two component flexible adhesive for applications requiring quick fixturing for higher throughput. SikaFast®-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 offers excellent adhesion to a wide variety of substrates with little or no surface preparation that cures rapidly at room temperature.
