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.
