SikaFast® 3121 Quick Seal, Dark Gray, 16.5 fl oz.

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.
