The separation required depends upon the materials, substrates,
     processes, and hygiene you have available.

     Silicone migration varies considerably between different materials.

     Silicone can migrate on operators hands and clothes. This is both
     material, soap and hygiene dependent.

     If you share benches, they must be cleaned prior to running the other
     material.

     With proper process and material controls, adjacent benches can work
     with most recently marketed materials. Without proper process
     controls, or with older silicone oil filled silicones, you may have to
     do the operation in separate buildings.
