I am trying to bond a piece of Duroid sheet to an aluminum surface. The Duroid is forced to a curved surface on the aluminum. I am pressing the Duroid sheet to match the aluminum's curved surface. It is being bonded with RTV (Momentive RTV88) and RTV Primer (Momentive SS4004P). After the 24 hour cure, we are seeing some delamination. I am looking for some ideas on how to correct the issue.
