Lap Shear Strength of Adhesives for Titanium

The graph below shows the lap shear strength of various Master Bond epoxy adhesives for titanium to titanium.

The coupons measured 4 x 1 x 1/16 inch. As preparation, their surfaces were roughened and cleaned with acetone. Supreme 10AOHT and Supreme 10HT present outstanding lap shear strength, not only for titanium but for other metals as well.

When choosing the proper adhesive, there are many other factors to consider, such as specific processing and operation conditions. For example if thermal conductivity is needed, Supreme 10AOHT may be desirable. If a room temperature cure is needed, EP21LV or Supreme 11HT may be better.
