Overview
3M™ Scotch-Weld™ 2216 Series structural epoxy adhesive is a flexible, two-part medium viscosity epoxy formulation, effectively reduces running, dripping or migration while also self-leveling. It has a flash point greater than or equal to 201 degrees F for part-A and 248 degrees C for part-B. The gray colored part-A liquid of epoxy adhesive has a pungent odor and 1.26 specific gravity. Gray colored part-B liquid of epoxy adhesive has a slight epoxy odor and 1.33 specific gravity. It has a density of 1.33 grams per milliliter for part-A and 1.26 grams per milliliter for part-B. The adhesive comes with a vapor pressure rating less than or equal to 0.1 millimeters Hg for part-A/B. This product has a viscosity of 40,000 to 80,000 centipoises for part-A and 75,000 to 150,000 centipoises for part-B. It takes a curing time of 7 days at 24 degrees C, 2 hours at 66 degrees C and 30 minutes at 93 degrees C. The epoxy compound requires an application time of 90 minutes. It has a peeling strength of 25 piw at 75 degrees F and a shear strength of 3200 psi. This product offers an area of coverage up to 320 square feet per gallon. The adhesive comes in a 1-quart kit and is rated at 60 to 80 degrees F for safe storage.
