Try contacting Humiseal. They are BIG in conformal coating materials: http://www.humiseal.com/

I wonder if anybody could spec a conformal coating or simalar application, to protect PCB's at 90% humidity. Standard HPA from electrolube does not work if the humidity is in excess of 75%. Cheers

Urethane CC have greater resistance to solvents than acrylic CC

we use humiseal for military a customer, in an aerosol can, gives good results

We are developing a new product that requires conformal coating on the motor controller. We selected a silicone based conformal coat due to its ease of use. There has been disagreement among engineers as to its impact on the motor. We have contact

We allow no silicone in our shop, because they ruin solderability.

Especially VCM - volatile condensable materials. Strictly verboten around optics.

We use nothing but silicones and have for at least the last 7 years. We don't have relays, but we do have motors. No issues with soldering, but our lines are constructed such that the last solder operation is a good distance from the coating or pot

I'm not that concerned about the solderability of the motor. Our customer is concerned about the outgassing of the conformal coat effecting the motor brushes. Silicone will break down into SiO2 and SiC will result from a spark between the brushes a
