I spoke to a tech rep at 3M today and found out that the 467/468 line of products is known as #467MP, #468MP. They recommended that the products would work with shrink type tension but that for a stretched diaphragm they would probably not hold. The recommended transfer tape for highest strength and most agressive grip is #9485 which is a 5 thou thick transfer product. This is also available in a 2 thou thickness called #9482. The thicker product was said to have about double the strength. I thought that I would pass this information along. 3M also advised that if the diaphragm/bond line could be wrapped over the edge of the stator frame then the strength of the bond would be significantly increased.
