Standard Test Method for Blocking Point of Potentially Adhesive Layers

Importancia y uso:

4.1 Since some potentially adhesive materials are both thermoplastic and hygroscopic, this test method provides means for estimating, on the same material, both thermoplastic and hygroscopic blocking. Because some requirements are more strict than others, two varying degrees of blocking are recognized and defined: (1) First degree blocking, and (2) Second degree blocking. Two types of blocking are covered: (1) Cohesive blocking, and (2) Adhesive blocking.
