Evaluation of polyglycidyl esters as cryogenic adhesives |
|
| Authors: | Stanley R. Sandler |
| Abstract: | Polyglycidyl esters of aromatic polycarboxylic acids were evaluated as adhesives for aluminum over the temperature range ?453 to +400°F. The esters were cured either with amines or anhydrides. Cyclopentanetetracarboxylic acid dianhydride was found to be a superior curing agent and gave adhesives with tensile shear strengths in excess of 1000 psi at 400°F. |
