Storage and Handling

Standard Shelf Life for 3M™ Scotch-Weld™ Epoxy Adhesive EC - 3501 B/A is 12 months from the date of shipment from 3M when

stored at 60 to 80°F (15 to 27°C) in its original unopened container.

During the storage, crystallization of the epoxy resin may occur, giving the epoxy resin (Part B) a grainy appearance. This condition is

reversible by heating the adhesive typically in the range of 120 to 140 °F (49 to 60 °C) for about 15 to 30 minutes and return epoxy resin

to a smooth appearance. No change in physical or mechanical properties will result from this reheating process.
