Ken -

We found it necessary to totally isolate the silicone conformal coating
process from all other processes to prevent cross contamination.  This
included the appllication area, coating mixing and spray equipment, spray
booths, curing ovens, etc.  To do otherwise poses a significant risk that
traces of silicone will migrate onto other products and interfere with
bonding of adhesives or coatings.

Regards - Kelly
