Detailed Product Description:

Scotch-Weld #2216 B/A is a clear  two-part epoxy structural adhesive that attains structural

properties after a room temperature cure.  It is formulated to give a combination of

very high peel strength along with excellent shear strength.  It is a perfect choice for

bonding dissimilar materials including aluminum, carbon fiber, fiberglass, steel, stainless, etc.

Scotch-Weld #2216 A/B is identical to Scotch-Weld Epoxy Adhesive EC-2216 B/A which is certified for aircraft and aerospace applications.  Scotch-Weld #2216 B/A may be used for aircraft and aerospace applications if proper Certificates of Test have been issued and material meets all aircraft manufacturer’s specification requirements. 

Precautions:

Can be an eye and skin irritant. 

Note that bond strength is only as good as adhesion to the adjoining substrates.  Follow manufacturer’s recommendations for surface preparation.

Packaging:

Resin comes packed in 2-ounce tube.  Hardener comes packed in 2-ounce tube.
