I have an application in which I have fully cured silicone molded parts. These are parts of a subassembly. The next operation of the manufacturing procedure involves passing this subassembly through a UV-cure cycle (for curing another part that has been glued on to this assembly). My question is whether exposing the silicone parts to this secondary UV-cure cycle might affect their properties in a certain way. Is there any harm in doing this? @ Ask The Experts

The short answer is, I do not “believe” it would affect the molded component of any significance or noticeable amount. However I don’t have experience with this and would refer you in this instance to a chemist at Dow Corning, Nusil, or Momentive silicones for a more in-depth response on how the chemistry may react or be affected within the material.
