Mornin' Kelly & All -

The first step is to get the details of exactly what silicone is being used
on this part from it's manufacturer - the resin formulation is critical to
determining the appropriate adhesive.  The second step is to contact
applications engineering at one of the major silicone resin formulators
(possibly the supplier of the resin used in this SRAM).  Provide them the
information regarding the parts resin composition, and the details of your
heatsink (materials and finish).  They will also need to know your intended
use environment - your own engineering department will have to assist on
determining adequacy of bond strength, etc., once compatible materials have
been recommended.

A word of caution: silicone adhesives are not noted for having tremendously
high bond strengths.

Regards - Kelly
