る。First, two adherends such as steel plates are prepared, and after polishing the adhesive surfaces of the adherends, the adhesive surfaces are degreased and cleaned. Next, after preparing the adhesive for the curing time measurement test by mixing the main component and curing agent, the adhesive is applied to the adhesive surface of the adherend, and the adhesive surface of the two adherends is coated. A test piece for measuring adhesive strength? The number of test pieces required to measure the curing time is prepared, and the test pieces thus prepared are measured at fixed time intervals using a tensile tester, etc. What is the relationship between adhesive strength and elapsed time? Is this test until there is no change in adhesive strength over time?
