migration

A condition or process of extraction, in which an aqueous or organic solvent selectively dissolves part of an adhesive film, and carries it to a different location as the solvent evaporates. The term also refers to the penetration of an adhesive plasticizer into the adherends due to the attraction of the adherend for the plasticizer. See also: ACID MIGRATION .
