Question: I am working on a prototype that involves bonding a silicone rubber to a pliable pvc surface and have had a difficult time bonding them together. Is there an adhesive you can recommend, that could assist me in this process?Answer: Although I have never attempted to bond/overmold silicone to polyvinyl chloride, I have had good results using other plastics.  Some processing techniques you may wish to consider incorporating into your process, are surface abrasion on the pvc (via sanding/sandblasting), the use of a self-bonding silicone material that contains adhesion promoters within it, the use of plasma treatment prior to the application of the silicone, and lastly, the application of a platinum primer to the substrate.
