Nine commercial adhesives based essentially on epoxy resins were evaluated for use in structural applications where the service temperatures may vary from 154c up to 250 c. The shear strength of the adhesive bonds to aluminum within a temperature range extending from -54 c to that temperature at which the bond strength would fall below 1000 psi was determined. A shear strength would fall below 1000 psi was determined. A shear strength of 1000 psi was arbitararily established as the minimum acceptable strength hence, testing of individual adhesives was discontinued at that point. The flexural strength of several of the adhesives was determined at 23 C. Author
