Hello.  We are considering a change in conformal coatings used on our
PCB's.  Currently in use are a silicone elastoplastic resin flow coating
and an acrylic spray coating.  We would like to switch to an automated
coating process using a low-VOC silicone elastoplastic resin and eliminate
the use of acrylics.  However, we expect to meet some resistance from our
customers, especially those in the paint industry, who think a silicone
coating will not perform as well in resisting paint and/or fuel oils.
Also, is there a possibility of silicone causing flaws in paint? (e.g.
coating with silicone resin a circuit board used in a paint sprayer.)  Any
feedback would be appreciated.
