Abstract

A workpiece composite includes a preform part and a gel accommodated in a recess in the preform, the recess being enclosed by at least one edge which serves as a creep barrier to prevent the gel from spreading. The at least one edge of the recess defines a termination point of at least one surface which is provided with a coating made of an oleophobic material in an area adjacent to the at least one edge.
