Standard Test Method for Flexibility Determination of Supported Adhesive Films by Mandrel Bend

Importancia y uso:

5.1 The mandrel bend test is simple and fast. It requires little investment in equipment and little operator training. The prime purpose is to determine whether a film of adhesive coated on a substrate meets flexibility requirements. The test is also useful for comparing flexibility of adhesives. It can be used to design adhesives by comparing the flexibility of various formulations to meet specific end-use parameters. The adhesive flexibility can be determined at temperatures other than ambient by conditioning the test apparatus and test specimen at the desired temperature and performing the test under those conditions.
