[Experimental studies on the hardness and adhesiveness of repair materials for metal ceramics]

This is a report of tests on the hardness and ability to adhere of materials which are recommended for the correction of cracked ceramic facings. The test for adhesiveness was carried out on three typical baked alloys and on a ceramic mass. Further tests were carried out to determine the influence of three Cyanoacrylate glues and a special adhesive agent. Results showed that all materials, especially the cyanoacrylate glues (excepting the adhesive agent) suffer from lowering of their adhesive capacity through the influence of moisture.
