I'm looking to adhere to a substrate which has a thin layer of fuser oil (poly dimethyl siloxane).  You can imagine that bonding to a silicone oil is a nightmare - but due to process condition restrictions it cannot simply be removed.  Is there an extrusion resin that may be laid down, and preferably heat-seal activated to get a "bite" into the fuser oil?          On another thought, is there perhaps a 'dessicant' additive that would dry up the oil per se, and allow for the normal adhesive component to go to work bonding?      Clear or transparent is preferred.  Thanks in advance.

I do not know of any resin in particular, but I suspect a silicone primer which adheres in spite of the silicone oil will not present an adhesive surface itself either.
One alternative way to accomplish this would be to carry out plasma treatment of the surface (and in effect burning or blasting away the siloxane film) prior to application of the adhesive.
