The 2216-Gray -2OZ is a flexible, two-part, room-temperature curing epoxy adhesive that provides high shear and peel strength, making this an ideal adhesive for the most demanding aerospace applications. The mix ratio is 2:3 and the adhesive provides a 90 minute work life to allow time to adjust fit prior to setting. The adhesive reaches handling strength in approximately 12 hours and is fully cured in 7 days (at 72° F /22° C), but can be accelerated with heat.
